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

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.

The efficacy of periprostatic local anaesthetic infiltration in transrectal ultrasound biopsy of prostate: a prospective randomised control study

Kuppusamy S, Faizal N, Quek KF, Razack AH, Dublin N

World J Urol, 2010 Dec;28(6):673-6.
PMID: 20623289 DOI: 10.1007/s00345-010-0578-7

It is still uncertain as to which form of anaesthesia is the optimum. We conducted a study to identify the best location and optimum volume of anaesthetic agent in order to achieve best pain relief and cooperation from our patients. We also assessed the need for local anaesthetic gel for probe lubrication and if the number of cores during biopsy makes a difference in the pain score.

Pain control after thoracotomy. An extrapleural tunnel to provide a continuous bupivacaine infusion for intercostal nerve blockade

Majid AA, Hamzah H

Chest, 1992 Apr;101(4):981-4.
PMID: 1555472

This study was undertaken to determine whether an infusion of local anesthetic (LA) delivered through an extrapleural tunnel could provide satisfactory control of pain in the postthoracotomy period. Twelve patients undergoing thoracotomy were studied. A T-shaped tunnel was created by elevating the parietal pleura at the posteromedial end of the thoracotomy wound. An irrigation catheter was then inserted and an infusion of bupivacaine commenced, initially at 5 mg/kg/24 h and subsequently at 3 mg/kg/24 h. Pain was well controlled in eight patients and satisfactory in four patients. The latter required one dose of opiate analgesia each in the 48-h postoperative period. We conclude that an infusion of bupivacaine into the extrapleural space is an effective means of control of pain after thoracotomy.

Trends and complications of local anaesthesia in cataract surgery: an 8-year analysis of 12 992 patients

Thevi T, Godinho MA

Br J Ophthalmol, 2016 Dec;100(12):1708-1713.
PMID: 26994109 DOI: 10.1136/bjophthalmol-2015-307785

BACKGROUND: Cataract surgery has progressed from large incision to smaller incisions, which do not require sutures. Anaesthesia too has progressed from general anaesthesia to local anaesthesia to topical anaesthesia. The ideal anaesthesia for cataract surgery would be one that is easy to administer, provides adequate pain relief during surgery and is associated with fewer complications.
AIMS: This study was done to find out the most suitable anaesthesia for patients with fewer complications and also to look at the trend of anaesthesia being used.
METHODS: A retrospective analysis was done of patients who underwent cataract surgery from 2007 to 2014 in Hospital Melaka. Data were obtained from the National Eye Database and analysed using SPSS. Trend of types of anaesthesia used and the associated complications with each were studied.
RESULTS: The most frequently used anaesthesia was topical anaesthesia, which showed an upward trend followed by subtenon in turn showing a downward trend. Subtenon anaesthesia was associated with more intraoperative and postoperative complications while topical anaesthesia was associated with fewer complications.
CONCLUSIONS: Topical anaesthesia has shown a steady increase in usage and is the ideal anaesthesia, which has been associated with fewer complications.

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.

Pre-emptive intraperitoneal local anaesthesia: an effective method in immediate post-operative pain management and metabolic stress response in laparoscopic appendicectomy, a randomized, double-blinded, placebo-controlled study

Thanapal MR, Tata MD, Tan AJ, Subramaniam T, Tong JM, Palayan K, et al.

ANZ J Surg, 2014 Jan-Feb;84(1-2):47-51.
PMID: 23057502 DOI: 10.1111/j.1445-2197.2012.06210.x

Although laparoscopic surgeries are associated with reduced surgical stress response and shortened post-operative recovery, intense pain and high analgesia requirements in the immediate post-operative period are often the chief complaints.
