Efficient halal bleeding, animal handling, and welfare: A holistic approach for meat quality

Aghwan ZA, Bello AU, Abubakar AA, Imlan JC, Sazili AQ

Meat Sci, 2016 Nov;121:420-428.
PMID: 27468102 DOI: 10.1016/j.meatsci.2016.06.028

Traditional halal slaughter and other forms of religious slaughter are still an issue of debate. Opposing arguments related to pre-slaughter handling, stress and pain associated with restraint, whether the incision is painful or not, and the onset of unconsciousness have been put forward, but no consensus has been achieved. There is a need to strike a balance between halal bleeding in the light of science and animal welfare. There is a paucity of scientific data with respect to animal welfare, particularly the use of restraining devices, animal handling, and efficient halal bleeding. However, this review found that competent handling of animals, proper use of restraining devices, and the efficient bleeding process that follows halal slaughter maintains meat eating quality. In conclusion, halal bleeding, when carried out in accordance with recommended animal welfare procedures, will not only maintain the quality and wholesomeness of meat but could also potentially reduce suffering and pain. Maintained meat quality increases consumer satisfaction and food safety.

PMID: 32471966

BACKGROUND: Procedural sedation and analgesia (PSAA) or monitoring anaesthesia care (MAC) must provide analgesia, amnesia and hypnosis with complete and rapid recovery that suits a particular operative procedure with minimum side effects. For a child undergoing a procedure, a major deciding factor is whether it is painful or not. Deep Sedation is required during the procedures to allay the anxiety, pain, and movement. The appropriate level of sedation depth will prevent consciousness, over-sedation, optimisation of dosage and prevents adverse complications. There are few studies about consciousness in pediatric patients during methotrexate injection with monitored anaesthesia care (MAC). The objective is to find out the incidence of consciousness of paediatric patients during methotrexate injection with Monitored Anaesthesia Care.
METHODS: Observational study conducted on 68 patients (1- 18 yrs.) with physical status of ASA II during methotrexate injection with MAC at the RSUP dr. Sardjito. The depth of anaesthesia was monitored with Observer's Alertness Assessment Sedation Scale (OAAS) every two minutes. Consciousness was defined as OAAS=5, or if there is volunteer movement of patients. The result was analysed and categorised according to age, sex, physical status, Body Mass Index (BMI) and anaesthesia's medication of patients.
RESULTS: Positive consciousness in paediatric patients based on OASS score at 2-minute and 4-minutes was 26.5% and 3.2% respectively, and was rescued by additional propofol 2mg/kg body weight.
CONCLUSION: The incidence of paediatric consciousness in patients during methotrexate injection with Monitored Anaesthesia Care (MAC) in the Sardjito General Hospital is 26.5% (2-minute after induction) and 3.2% (4-minute after induction), and this is considerably high thus needing futher prevention.

Fulltext Ocular Blood Flow in Rabbits under Deep Anesthesia: A Real-Time Measurement Technique and Its Application in Characterizing Retinal Ischemia

Bhatti MS, Tang TB, Chen HC

Sci Rep, 2018 04 09;8(1):5713.
PMID: 29632320 DOI: 10.1038/s41598-018-24141-4

In this study, we reported a new technique based on laser speckle flowgraphy to record the ocular blood flow in rabbits under deep anesthesia, and proposed parameters to characterize retinal ischemia. We applied the proposed technique to study the correlation of blood flow between the eyes of normal non-anesthetized animals, and to characterize the occlusion of the internal carotid artery (ICA) and external carotid artery (ECA). We established a correlation in blood flow between the eyes of non-anesthetized animals, and derived two new parameters, namely, the laterality index and vascular perfusion estimate (VPE). Our experimental results from 16 eyes (of 13 New Zealand white rabbits) showed a reduction in ocular blood flow with a significant decrease in the VPE after the occlusion of the ECA (p anesthesia by using laser speckle flowgraphy and the VPE as an indicator of successful occlusion. The proposed technique might be applicable in quantifying the efficacy of new drugs and interventions for the treatment of retinal ischemia.

Comparing the outcome of monitored anaesthesia care and local anaesthesia for carpal tunnel syndrome surgery by neurosurgeons

Goh CH, Lau BL, Teong SY, Law WC, Tan CS, Vasu R, et al.

Med J Malaysia, 2019 12;74(6):499-503.
PMID: 31929475

INTRODUCTION: Carpal tunnel syndrome (CTS) is the commonest median nerve entrapment neuropathy of the hand, up to 90% of all nerve compression syndromes. The disease is often treated with conservative measures or surgery. The senior author initially intended to treat his own neurosurgical patients concurrently diagnosed with carpal tunnel syndrome in 2014, subsequently, he began to pick up more referrals from the primary healthcare group over the years. This has led to the setup of a peripheral and spine clinic to act as a hub of referrals.
OBJECTIVE: Department of Neurosurgery Sarawak aimed to evaluate the surgical outcome of carpal tunnel release done over five years.
METHODS: The carpal tunnel surgeries were done under local anaesthesia (LA) given by neurosurgeons (Bupivacaine 0.5% or Lignocaine 2%). Monitored anaesthesia care (MAC) was later introduced by our hospital neuroanaesthetist in the beginning of 2018 (Target-controlled infusion propofol and boluses of fentanyl). We looked into our first 17 cases and compared these to the two anaesthesia techniques (LA versus MAC + LA) in terms of patient's pain score based on visual analogue scale (VAS).
RESULTS: Result showed MAC provided excellent pain control during and immediately after the surgery. None experienced anaesthesia complications. There was no difference in pain control at post-operation one month. Both techniques had equal good clinical outcome during patients' clinic follow up.
CONCLUSION: Neurosurgeons provide alternative route for CTS patients to receive surgical treatment. Being a designated pain free hospital, anaesthetist collaboration in carpal tunnel surgery is an added value and improves patients overall experience and satisfaction.

Fulltext Combined spinal-epidural analgesia in labour: its effects on delivery outcome

Singh SK, Yahya N, Misiran K, Masdar A, Nor NM, Yee LC

Braz J Anesthesiol, 2016 May-Jun;66(3):259-64.
PMID: 27108822 DOI: 10.1016/j.bjane.2014.09.006

BACKGROUND AND OBJECTIVES: Combined spinal-epidural (CSE) has become an increasingly popular alternative to traditional labour epidural due to its rapid onset and reliable analgesia provided. This was a prospective, convenient sampling study to determine the effects of CSE analgesia on labour outcome.

METHODS: One hundred and ten healthy primigravida parturients with a singleton pregnancy of ≥37 weeks gestation and in the active phase of labour were studied. They were enrolled to the CSE (n=55) or Non-CSE (n=55) group based on whether they consented to CSE analgesia. Non-CSE parturients were offered other methods of labour analgesia. The duration of the first and second stage of labour, rate of instrumental vaginal delivery and emergency cesarean section, and Apgar scores were compared.

RESULTS: The mean duration of the first and second stage of labour was not significantly different between both groups. Instrumental delivery rates between the groups were not significantly different (CSE group, 11% versus Non-CSE group, 16%). The slightly higher incidence of cesarean section in the CSE group (16% versus 15% in the Non-CSE group) was not statistically significant. Neonatal outcome in terms of Apgar score of less than 7 at 1 and 5min was similar in both groups.

CONCLUSION: There were no significant differences in the duration of labour, rate of instrumental vaginal delivery and emergency cesarean section, and neonatal outcome in parturients who received compared to those who did not receive CSE for labour analgesia.

Fulltext Critical incident monitoring in anaesthesia (1)

Choy YC

Med J Malaysia, 2006 Dec;61(5):577-85.
PMID: 17623959

Critical incident monitoring in anaesthesia is an important tool for quality improvement and maintenance of high safety standards in anaesthetic services. It is now widely accepted as a useful quality improvement technique for reducing morbidity and mortality in anaesthesia and has become part of the many quality assurance programmes of many general hospitals under the Ministry of Health. Despite wide-spread reservations about its value, critical incident monitoring is a classical qualitative research technique which is particularly useful where problems are complex, contextual and influenced by the interaction of physical, psychological and social factors. Thus, it is well suited to be used in probing the complex factors behind human error and system failure. Human error has significant contributions to morbidities and mortalities in anaesthesia. Understanding the relationships between, errors, incidents and accidents is important for prevention and risk management to reduce harm to patients. Cardiac arrests in the operating theatre (OT) and prolonged stay in recovery, constituted the bulk of reported incidents. Cardiac arrests in OT resulted in significant mortality and involved mostly de-compensated patients and those with unstable cardiovascular functions, presenting for emergency operations. Prolonged-stay in the recovery extended period of observation for ill patients. Prolonged stay in recovery was justifiable in some cases, as these patients needed a longer period of post-operative observation until they were stable enough to return to the ward. The advantages of the relatively low cost, and the ability to provide a comprehensive body of detailed qualitative information, which can be used to develop strategies to prevent and manage existing problems and to plan further initiatives for patient safety makes critical incident monitoring a valuable tool in ensuring patient safety. The contribution of critical incident reporting to the issue of patient safety is far from clear and very difficult to study. Efforts to do so have tended to rely on incident reporting, the only practical approach when funding is limited. The heterogeneity of critically ill patients as a group means that huge study populations would be required if other research techniques were to be used. In the era of evidence-based medicine, anaesthetists are looking for alternative evidence-based solutions to problems that we have accepted traditionally when we cannot quantify for good practical reasons. In the quest for patient safety, investment should be made in reliable audit, detection and reporting systems. The growing recognition that human error usually result from a failure of a system rather than an individual should be fostered to allow more lessons to be learnt, an approach that has been successful in other, safety-critical industries. New technology has a great deal to offer and investment is warranted in novel fail-safe drug administration systems. Last but not the least the importance of simple and sensible changes and better education should be remembered.

Fulltext Prolonged paralysis with atracurium use in a patient with Rubinstein-Taybi syndrome

Dharmalingam TK, Liew Sat Lin C, Muniandy RK

BMJ Case Rep, 2018 Feb 22;2018.
PMID: 29472422 DOI: 10.1136/bcr-2017-222692

Rubinstein-Taybi syndrome (RTS) is a rare autosomal dominant disorder that occurs due to a microdeletion of chromosome 16p13. The craniofacial abnormalities in these patients may pose a challenge for anaesthetist performing tracheal intubation. However, there are no known reported cases of drug interaction with non-depolarising muscle relaxant in patients with RTS. This young patient with RTS presented with an unexpected prolonged atracurium effect during the course of anaesthesia. After ruling out other possible causes, we have come to a conclusion that RTS itself could have played a role in the prolonged effect of atracurium. However, further studies will be needed to confirm this hypothesis. In the meantime, care should be used when using muscle relaxants in patients with RTS.

Effect of oral premedication on the anaesthetic efficacy of inferior alveolar nerve block in patients with irreversible pulpitis - A systematic review and network meta-analysis of randomized controlled trials

Pulikkotil SJ, Nagendrababu V, Veettil SK, Jinatongthai P, Setzer FC

Int Endod J, 2018 Sep;51(9):989-1004.
PMID: 29480930 DOI: 10.1111/iej.12912

This systematic review (SR; PROSPERO database: CRD42017075160) and network meta-analysis (NMA) identified the most effective oral premedication for anaesthetic success of inferior alveolar nerve blocks (IANB) in cases of irreversible pulpitis. Medline and Ebscohost databases were searched up until 10/2017. Randomized controlled trials (RCT) studying the effect of oral premedication, alone or in combination, on the success of IANB for cases of irreversible pulpitis, compared to placebo or other oral premedications, were included. Quality of the included studies was appraised by the revised Cochrane risk of bias tool for randomized trials. Pairwise analysis, NMA and quality of evidence assessment using GRADE criteria were performed. Nineteen studies (n = 1654 participants) were included. NMA demonstrated that compared to placebo, dexamethasone was most effective in increasing anaesthetic success (RR, 2.92 [95% CI 1.74,4.91]; SUCRA = 0.96), followed by NSAIDs (RR, 1.92 [95% CI 1.63,2.27], SUCRA = 0.738) and Tramadol (RR, 2.03 [95% CI 1.18,3.49], SUCRA = 0.737). Premedication with acetaminophen added to NSAIDs demonstrated similar efficacy as NSAIDs alone (RR, 1.06 [95% CI 0.79,1.43]). Sensitivity analyses proved the superiority of dexamethasone or NSAIDs over any other premedications. Subgroup analyses of specific dosages in comparison with placebo demonstrated that dexamethasone 0.5 mg was most effective, followed by ketorolac 10 mg, piroxicam 20 mg, ibuprofen 400 mg + acetaminophen 500 mg and Tramadol 50 mg. Ibuprofen 400 mg, 600 mg and 800 mg had a significantly improved IANB success, while Ibuprofen 300 mg had no effect. Oral premedication with dexamethasone, NSAIDs or Tramadol significantly increased anaesthetic success. More trials are needed to evaluate the premedication effects of dexamethasone or Tramadol for improved anaesthetic success of IANB when treating irreversible pulpitis.

Fulltext Topical nasal anaesthesia for fibreoptic bronchoscopy: lignocaine spray or gel?

Zainudin BM, Rafia MH, Sufarlan AW

Singapore Med J, 1993 Apr;34(2):148-9.
PMID: 8266157

Lignocaine spray for anaesthetising the nasal mucosa for fibreoptic bronchoscopy often causes discomfort to the patient. We compared two techniques of applying nasal topical anaesthesia using either lignocaine spray (group A: 25 patients) or gel (group B: 30 patients) to assess patients' tolerance to the procedure. Both groups received 100 mg of lignocaine in the nostril, 40-50 mg to oropharynx, 120 mg to vocal cords and 40-100 mg to trachea and bronchi. Throat anaesthesia was the most common unpleasant part experienced by both groups of patients (34.5%), followed by examination of bronchi (30.6%) and nasal anaesthesia (21.8%). Significantly more patients in group A experienced discomfort or pain during nasal anaesthesia as compared to group B (p < 0.001). Patients' tolerance to the bronchoscopy was similar in both groups and the examination was performed satisfactorily in all patients. Thus, lignocaine gel is a simple technique, effective and less irritating as compared to lignocaine spray for topical nasal anaesthesia.

Reddy SV, Sein K

Singapore Med J, 1991 Feb;32(1):29-30.
PMID: 2017701

Sixty patients who received massive blood transfusion intraoperatively and/or in the immediate post-operative period were analysed. Six patients had hypokalemia and two had hyperkalemia. The multifactorial changes leading to electrolyte disturbances especially involving potassium are discussed in relation to hypotension, hypothermia, acidosis, pH, and release of catecholamine. Potassium changes in relation to anaesthesia are discussed. The danger of routine administration of calcium during massive blood transfusion is stressed.

Fulltext A Developing Nation's Experience in Using Simulation-Based Training as a Preparation Tool for the Coronavirus Disease 2019 Outbreak

Loh PS, Chaw SH, Shariffuddin II, Ng CC, Yim CC, Hashim NHM

Anesth Analg, 2021 Jan;132(1):15-24.
PMID: 33002931 DOI: 10.1213/ANE.0000000000005264

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic affected and overwhelmed many health care systems around the world at an unprecedented speed and magnitude with devastating effects. In developing nations, smaller hospitals were unprepared to face this outbreak nor had strategies in place to do so at the beginning. Here, we describe the preparation in an anesthetic department using simulation-based training over 2 weeks, as the number of cases rose rapidly.
METHODS: Three areas of priority were identified as follows: staff safety, patient movement, and possible clinical scenarios based on simulation principles in health care education. Staff was rostered and rotated through stations for rapid-cycle deliberate practice to learn donning and doffing of personal protective equipment (PPE) and powered air-purifying respirator (PAPR). For difficult airway management, Peyton's 4 steps for skills training and Harden's Three Circle model formed the structure in teaching the core skills. Several clinical scenarios used system probing to elicit inadequacies followed by formal debriefing to facilitate reflection. Finally, evaluation was both immediate and delayed with an online survey after 1 month to examine 4 levels of reaction, learning, behavior, and impact based on the Kirkpatrick Model. Frequency and thematic analysis were then conducted on the quantitative and qualitative data, respectively.
RESULTS: A total of 15 of 16 (93%) consultants, 16 (100%) specialists, and 81 (100%) medical officers in the department completed training within 2 consecutive weeks. Reaction and part of the learning were relayed immediately to trainers during training. In total, 42 (39%) trained staff responded to the survey. All were satisfied and agreed on the relevance of training. A total of 41 respondents (98%; 95% confidence interval [CI], 87-99) answered 16 of 20 questions correctly on identifying aerosol-generating procedures (AGP), indications for PPE, planning and preparation for airway management to achieve adequate learning. About 43% (95% CI, 27-59) and 52% (95% CI, 36-68) recalled donning and doffing steps correctly. A total of 92 responses from 33 respondents were analyzed in the thematic analysis. All respondents reported at least 1 behavioral change in intended outcomes for hand hygiene practice (20%), appropriate use of PPE (27%), and airway management (10%). The emerging outcomes were vigilance, physical distancing, planning, and team communication. Finally, the impact of training led to the establishment of institutional guidelines followed by all personnel.
CONCLUSIONS: Simulation-based training was a useful preparation tool for small institutions with limited time, resources, and manpower in developing nations. These recommendations represent the training experience to address issues of "when" and "how" to initiate urgent "medical education" during an outbreak.

Fulltext Electroencephalographic changes associated with antinociceptive actions of lidocaine, ketamine, meloxicam, and morphine administration in minimally anaesthetized dogs

Kaka U, Hui Cheng C, Meng GY, Fakurazi S, Kaka A, Behan AA, et al.

Biomed Res Int, 2015;2015:305367.
PMID: 25695060 DOI: 10.1155/2015/305367

Effects of ketamine and lidocaine on electroencephalographic (EEG) changes were evaluated in minimally anaesthetized dogs, subjected to electric stimulus. Six dogs were subjected to six treatments in a crossover design with a washout period of one week. Dogs were subjected to intravenous boluses of lidocaine 2 mg/kg, ketamine 3 mg/kg, meloxicam 0.2 mg/kg, morphine 0.2 mg/kg and loading doses of lidocaine 2 mg/kg followed by continuous rate infusion (CRI) of 50 and 100 mcg/kg/min, and ketamine 3 mg/kg followed by CRI of 10 and 50 mcg/kg/min. Electroencephalogram was recorded during electrical stimulation prior to any drug treatment (before treatment) and during electrical stimulation following treatment with the drugs (after treatment) under anaesthesia. Anaesthesia was induced with propofol and maintained with halothane at a stable concentration between 0.85 and 0.95%. Pretreatment median frequency was evidently increased (P < 0.05) for all treatment groups. Lidocaine, ketamine, and morphine depressed the median frequency resulting from the posttreatment stimulation. The depression of median frequency suggested evident antinociceptive effects of these treatments in dogs. It is therefore concluded that lidocaine and ketamine can be used in the analgesic protocol for the postoperative pain management in dogs.

Plating of Distal Radius Fracture Using the Wide-Awake Anesthesia Technique

Ahmad AA, Yi LM, Ahmad AR

J Hand Surg Am, 2018 Nov;43(11):1045.e1-1045.e5.
PMID: 29866390 DOI: 10.1016/j.jhsa.2018.03.033

Fractures of the distal radius are one of the most common types of injuries encountered in hand surgery. Plate osteosynthesis is recommended for unstable fractures. Because distal radius fracture fixation is usually performed under general or regional anesthesia with the use of a tourniquet, this exposes patients, especially elderly people with extensive comorbidities, to adverse effects commonly associated with these forms of anesthesia. As such, many of these patients are unable to undergo surgery in a timely manner until they are deemed medically fit for surgery or anesthesia, and some may still be treated nonsurgically. Injecting local anesthetic of lidocaine and epinephrine into the surgical field and without using a tourniquet is known to be advantageous for various surgical procedures of the hand. However, this approach, also known as wide-awake local anesthesia no tourniquet (WALANT), has not been used in the fixation of fractures beyond the wrist. Using the WALANT approach as an alternative anesthetic for plating of distal radius fractures may enable patients who are normally denied surgery owing to their age or medical comorbidities to undergo plate fixation for the fractures. This article outlines the WALANT approach used for a single case of fixation of distal end radius fracture with a detailed description of the technique of administering local anesthesia.

PMID: 19110718

Collection of biological samples from pteropid bats requires chemical restraint of the bats to minimize risks to humans and stress to the bat. The effectiveness of an intravenous combination of ketamine and xylazine for short-term restraint of wild-caught variable flying foxes (Pteropus hypomelanus) in a field situation was evaluated. Eight adult male variable flying foxes were injected intravenously with 0.1 ml of ketamine and xylaxine containing 5 mg of ketamine and 1 mg of xylazine. The mean induction time was 80 +/- 20 sec, and mean immobilization time was 26 +/- 10 min. The ketamine-xylazine combination used in this study produced effective short-term immobilization of wild variable flying foxes for the collection of biological samples.

Transient loss of power of accommodation in 1 eye following inferior alveolar nerve block: report of 2 cases

Ngeow WC, Shim CK, Chai WL

J Can Dent Assoc, 2006 Dec;72(10):927-31.
PMID: 17187708

Unintended intravascular injection from inferior alveolar nerve blocks can result in frustrating distant complications affecting such structures as the middle ear and eyes. Possible complications affecting the eyes include blurring of vision, diplopia, mydriasis, palpebral ptosis and amaurosis (temporary or permanent). In this article, we present a complication that has been reported only rarely. Two patients developed transient loss of power of accommodation of the eye resulting in blurred vision after routine inferior alveolar nerve blocks on the ipsilateral side. Clear vision returned within 10-15 minutes after completion of the blocks. The possible explanation for this phenomenon is accidental injection into the neurovascular bundle of local anesthetic agents, which were carried via the blood to the orbital region. This resulted in paralysis of a branch of cranial nerve III, the short ciliary nerves that innervate the ciliary muscle, which controls accommodation.

A comparative study of sevoflurane sedation with nitrous oxide sedation for dental surgery

Wang CY, Chiu CL, Har KO, Chan C, Rahman ZA

Int J Oral Maxillofac Surg, 2002 Oct;31(5):506-10.
PMID: 12418566

This study compares the use of inhalation sedation using sevoflurane (group S) with inhalation sedation using nitrous oxide (group N) in patients undergoing bilateral extraction of third molar teeth under local anaesthesia. The study was designed as a cross-over study. Seventeen ASA I, day surgery patients were studied. Patients were randomly allocated to receive either 8 l/min 50% nitrous oxide in oxygen (group N) or same flow of 1% sevoflurane (group S) for the first procedure. Each patient then had the alternate method of sedation for the second procedure. There were no significant differences between the methods in patient co-operation and surgeon's satisfaction with sedation. Psychomotor tests were comparable in both groups. The patients were significantly more sedated in the group S compared to group N (P=0.004). Significantly more patients complained of an unpleasant odour group S (P<0.01) but none withdrew from the study for this reason. No adverse cardiorespiratory effects resulted from sevoflurane or nitrous oxide sedation. Both methods gave good amnesia during the procedure. There was high acceptance of both methods and the patients rated the technique as equally satisfactory. We conclude that inhalation sedation with sevoflurane is a suitable alternative method to nitrous oxide sedation.

The effectiveness of sub-Tenon's infiltration of local anaesthesia for cataract surgery

Verghese I, Sivaraj R, Lai YK

Aust N Z J Ophthalmol, 1996 May;24(2):117-20.
PMID: 9199741

PURPOSE: To determine if adequate anesthesia and akinesia could be obtained using an inferonasal quadrant sub-Tenons anaesthesia for cataract surgery.
METHODS: The sub-Tenons method of local anaesthesia was used in 50 patients undergoing extracapsular cataract extraction and lens implantation. The technique following was that described by JD Stevens in his study of 50 patients. Posterior sub-Tenons space was approached through a conjunctival incision in the inferonasal quadrant and the anaesthetic solution delivered by an irrigating cannula. The patients were assessed for residual ocular movements just before surgery. Effectiveness of anaesthesia was assessed during surgery using a verbal pain rating score. Scoring was based on the concept of a visual analogue pain score chart.
RESULTS: Total akinesia was obtained in 20% patients and total anaesthesia in 24% patients. The remainder of the patients had adequate akinesia and anaesthesia to proceed with and complete the surgery.
CONCLUSION: This method provides satisfactory anaesthesia for cataract surgery.

PMID: 27099663

Bertolotti's syndrome must be considered as a differential diagnosis for lower back pain in young people. Treatment, whether conservative or operative, is still debatable. In this paper, we report a case of a 20-year-old girl presenting with lower back pain for 8 years. We administered injection with local anaesthetic and steroid injections within the pseudo-articulation; however, the pain was relieved for 3 weeks. Surgical excision of the pseudo-articulation successfully treated her back pain and the sciatica.
