Fulltext Shortening the onset time of atracurium for rapid tracheal intubation

Jaradi H, Tay KH, Delilkan AE

Med J Malaysia, 1989 Jun;44(2):143-6.

PMID: 2626122

The 'Priming principle' applied to non-depolarizing muscle relaxant atracurium was studied in 60 patients. This was a double blind study. The conditions observed for intubation were graded and the efficacy of priming dose of atracurium for shortening the onset time of intubation was studied. The patients were of ASA classification I and II and received standard premedication. The purpose of the study was to use the priming dose of atracurium to shorten the onset time of intubating dose of atracurium. This would be desirable in conditions requiring rapid intubation and in situations when the depolarizing muscle relaxant suxamethonium is contra-indicated. The results were statistically significant.

Fulltext Fibreoptic intubation--a case series and brief review

Tan I, Wang CY

Med J Malaysia, 1993 Jun;48(2):200-6.

PMID: 8350796

Fibreoptic intubation has been established as a major advance in the management of difficult or failed intubation in the awake patient. If necessary, it may be performed under general anaesthesia with either spontaneous or controlled ventilation. This should be considered early in the management of failed intubation, before multiple attempts with other techniques lead to haemorrhage and oedema in the airway. We describe here selected case reports to illustrate this in 8 different situations. This is followed by a brief review of the technique and indications of fibreoptic intubation.

PMID: 8357487

A 27-year old male sustained a 60 per cent TBSA burn with inhalation injury following a road traffic accident. He developed respiratory distress on day 3 postburn, and was intubated and ventilated. He was noted to have greenish aspirate from his trachea on day 17 of ventilation. He succumbed from sepsis and died on day 21 post injury. At post-mortem, a large tracheo-oesophageal fistula (TOF) was found at the level of the cuff of the nasotracheal tube.

Fulltext Comparison of two bolus doses of esmolol for attenuation of haemodynamic response to tracheal intubation

Sharma S, Ghani AA, Win N, Ahmad M

Med J Malaysia, 1995 Dec;50(4):372-6.

PMID: 8668059

This prospective study was designed to compare the effectiveness of esmolol (either 100 mg or 200 mg) with a placebo in blunting the haemodynamic response to laryngoscopy and intubation. Seventy-five patients of ASA I or II scheduled for routine-surgery were selected and entered into a placebo-controlled study. Patients were randomly allocated to receive placebo, 100 mg or 200 mg of esmolol IV as part of an anaesthetic induction technique. There were no significant differences in the demographic distribution of the patients in the study. There was no statistical difference in the baseline heart rate (HR) and systolic blood pressure (SBP) between the three groups. One minute after the administration of the drug (prior to intubation) the differences in HR between the placebo group and both the 100 mg and 200 mg groups were significant (p < 0.05), and also at 1 min and 2 min following intubation for the 200 mg group (p < 0.05). In the 200 mg group there was a significant decrease, compared with placebo, in SBP at 1 min (p < 0.05) and at 2 min (p < 0.05) after intubation. In this study, adequate haemodynamic control following was obtained with the administration of 200 mg of esmolol.

Intubation without muscle relaxant: an alternative technique for rapid tracheal intubation

Wong AK, Teoh GS

Anaesth Intensive Care, 1996 Apr;24(2):224-30.

PMID: 9133197

The quality of laryngoscopy and tracheal intubation with propofol augmented by alfentanil was investigated as an alternative technique for rapid tracheal intubation. 119 patients aged between 18 and 60 years (ASA 1 and 2) undergoing elective surgery were prospectively studied in a randomized double-blind controlled fashion. Tracheal intubation facilitated by suxamethonium 1.0 mg/kg alfentanil 15 mu g/kg alfentanil 30 mu g/kg or saline control was compared after propofol induction. The quality of laryngoscopy and intubation were graded according to jaw relaxation, ease of insertion of the endotracheal tube and coughing on intubation. Failure to intubate occurred in 4% and 17% with alfentanil 15 mu g/kg and saline control respectively Tracheal intubation was successful in all patients with alfentanil 30 mu g/kg and suxamethonium 1.0 mg/kg. Alfentanil 15 mu g/kg was not statistically significantly different from saline (P = 0.112). Alfentanil 30 mu g/kg provided similar overall intubating conditions (P = 0.5) to suxamethonium 1.0 mg/kg. Alfentanil in both dosages effectively attenuated the haemodynamic responses to laryngoscopy and tracheal intubation.

Fulltext Endotracheal tube ignition during CO2 laser surgery of the larynx

Chiu CL, Khanijow V, Ong G, Delilkan AE

Med J Malaysia, 1997 Mar;52(1):82-3.

PMID: 10968058

We report a case of endotracheal tube fire occurring during CO2 laser surgery of the larynx. The ignition of an endotracheal tube was thought to be caused by laser penetration of an unprotected portion of the tube during resection of vocal cord tumour. Fire hazard is inevitable when a laser is used in the path of combustible gases and in the presence of flammable objects. We discuss the methods of prevention that were used.

The effect of mivacurium pretreatment on intra-ocular pressure changes induced by suxamethonium

Chiu CL, Lang CC, Wong PK, Delilkan AE, Wang CY

Anaesthesia, 1998 May;53(5):501-5.

PMID: 9659028

Forty patients without eye disease, undergoing elective nonophthalmic surgery, were studied in a double-blind, randomised, placebo-controlled study evaluating the efficacy of mivacurium pretreatment in attenuating the rise in intra-ocular pressure in response to suxamethonium administration, laryngoscopy and intubation. The patients were randomly allocated to receive either mivacurium 0.02 mg.kg-1 or normal saline as pretreatment 3 min before a rapid sequence induction technique using alfentanil, propofol and suxamethonium. Suxamethonium induced a significant increase in intra-ocular pressure in the control group but not in the mivacurium pretreatment group (mean (SEM) increase = 3.5 (1.2) mmHg vs. 0.4 (0.8) mmHg, p < 0.05). There was a decrease in intra-ocular pressure in both groups after laryngoscopy and intubation with no significant difference between the two groups. These results show that mivacurium pretreatment is effective in preventing the increase in intra-ocular pressure after suxamethonium administration.

Paediatr Anaesth, 1998;8(4):337-40.

PMID: 9672933

Congenital laryngotracheo-oesophageal cleft is a rare anomaly which presents a challenge to the anaesthetists because of the potential problems of establishing and maintaining an airway. We report the anaesthetic management of a one-month old baby with complete or type IV laryngotracheo-oesophageal presenting for the repair of the defect. The management of the precarious airway is presented and the various techniques of managing the airway are reviewed.

Alfentanil for intubation under halothane anaesthesia in children

NG KP, Wang CY

Paediatr Anaesth, 1999;9(6):491-4.

PMID: 10597551

Intubating conditions under halothane anaesthesia aided with alfentanil 20 micrograms.kg-1 were compared with suxamethonium 2 mg.kg-1 in 40 children presenting for day dental procedures. The condition of vocal cords, jaw relaxation and presence of movement and coughing were scored to give the overall intubating conditions. Successful intubation was achieved in 100% of the suxamethonium group and 94.7% of the alfentanil group. The cardiovascular response to intubation was attenuated in the alfentanil group. Some 43.7% of those receiving suxamethonium developed myalgia the day after surgery compared with 0% in the alfentanil group (P < 0.01).

Subcutaneous emphysema and pneumomediastinum after endotracheal anaesthesia

Chiu CL, Ong GS

Ann Acad Med Singap, 2000 Mar;29(2):256-8.

PMID: 10895351

INTRODUCTION: We report a case of subcutaneous emphysema and pneumomediastinum that presented postoperatively after tracheal extubation.

CLINICAL PICTURE: A 51-year-old man had an uneventful anaesthesia lasting about 6.5 hours. Intubation was performed by a very junior medical officer and was considered difficult. He developed sore throat, chest pain, numbness of both hands and palpable crepitus around the neck postoperatively. Chest X-ray revealed diffuse subcutaneous emphysema, pneumomediastinum and possible pneumopericardium.

TREATMENT: He was treated conservatively with bed rest, oxygen, analgesia, antibiotic prophylaxis, reassurance and close monitoring.

OUTCOME: The patient made an uneventful recovery.

CONCLUSIONS: We discussed the possible causes.
