Randomized Controlled Trial Comparative StudyRandomised comparison of the Classic Laryngeal Mask Airway with the Cobra Perilaryngeal Airway during anaesthesia in spontaneously breathing adult patients.
We tested the hypothesis that the Cobra Perilaryngeal Airway (PLA) with its high volume low-pressure cuff would provide superior airway leakage pressure compared with the Classic Laryngeal Mask Airway (LMA) in spontaneously breathing adult patients. Ninety consecutive adult patients were randomly allocated to receive one of these two supralaryngeal devices. The airway leakage pressure was higher for the PLA compared with the LMA (22 +/- 9 cmH2O vs. 18 +/- 6 cmH2O; P < 0.05). ⋯ The number of attempts required to achieve successful insertion and the incidence of postoperative complications were similar in both groups. The findings suggest that the PLA provides a superior airway seal at a lower intracuff pressure compared to the LMA. However the time for successful insertion may be increased.

Dose-related effect of propofol on pancreatic enzymes and triglyceride levels in patients undergoing non-abdominal surgery.
Various case reports have indicated a possible relationship between propofol and pancreatitis. However, it is not clear whether this relationship (if any) is dose-related or idiosyncratic. Therefore, a prospective study was conducted to evaluate the effect of different doses of propofol on postoperative pancreatic enzymes and serum triglyceride levels. ⋯ These values did not differ significantly in between the groups even despite the significantly different doses of propofol in the three groups (P < 0.001). None of the patients in the three groups developed any feature suggestive of acute pancreatitis in the postoperative period. These findings indicate that propofol administration at recommended doses does not produce dose-related increases in pancreatic enzyme and triglyceride levels in ASA physical status I and II patients.

Case ReportsThe use of "ketofol" (ketamine-propofol admixture) infusion in conjunction with regional anaesthesia.
We present four patients in whom a "ketofol" (ketamine 200 mg and propofol 200 mg) infusion was used in conjunction with regional anaesthesia. The patients were considered 'high risk' due to their medical condition or age. The ketofol proved safe and effective in all four cases. Advantages of this technique included analgesia, airway preservation, maintenance of spontaneous respiration, haemodynamic stability and rapid recovery.

Comparative StudyDose requirements for propofol anaesthesia for dental treatment for autistic patients compared with intellectually impaired patients.
We had clinical grounds to suspect that patients with autism had greater propofol requirements during dental procedures than patients with intellectual impairment without autism. This hypothesis was tested by an audit of a standard anaesthetic technique. The audit was approved by our Hospital Ethics Committee. ⋯ The propofol infusion rates of the intellectually impaired group showed significant decline with age (propofol rate of requirement mg x kg(-1) x h(-1), mean [SD]): < six years 13.6 (3.6), seven to 19 years 9.5 (3.0) (P = 0.008 cf < six years group), > 19 years group 8.5 (2.4) (P = 0.001 cf < six years group). The propofol requirement was greater in the autism group than in the intellectual disability group, and the proportion of the cases where bolus propofol administration was needed after induction was significantly higher in the autistic patient group than in the intellectually impaired patients (P < 0.002). This suggests that autistic patients have greater propofol requirements for anaesthesia during ordinary dental treatment compared with intellectually impaired patients.
