Randomized Controlled Trial Clinical Trial
Optimal dose of lignocaine for preventing pain on injection of propofol.
The purpose of this study was to define the optimum dose of lignocaine required to reduce pain on injection of propofol. We conducted a prospective, randomized, double-blind trial on 310 patients undergoing anaesthesia. Patients were allocated to four groups according to the lignocaine dosage: group A (control), no lignocaine; group B, lignocaine 0.1 mg kg-1; group C, lignocaine 0.2 mg kg-1; group D, lignocaine 0.4 mg kg-1. Our results showed that a dose of lignocaine 0.1 mg kg-1 significantly reduced the incidence of pain and that there was no improvement when the dose was increased.

Randomized Controlled Trial Comparative Study Clinical Trial
Anesthesia for craniotomy: total intravenous anesthesia with propofol and alfentanil compared to anesthesia with thiopental sodium, isoflurane, fentanyl, and nitrous oxide.
To compare a total intravenous (IV) anesthetic technique based on propofol and alfentanil with a commonly used anesthetic technique for craniotomy. ⋯ A total IV anesthetic technique with propofol and alfentanil is a valuable alternative to a more commonly used technique based on thiopental sodium, N2O, fentanyl, and isoflurane.

Propofol was used for the induction and maintenance of anesthesia in a patient undergoing a laparoscopic tubal ligation. This new anesthetic has not been associated with postoperative ventricular arrhythmias. This report demonstrates the occurrence of supraventricular tachycardia deteriorating to ventricular tachycardia in a patient who received propofol. Included is a discussion of the possible causes of this event.

The anesthetic technique chosen for a malignant hyperthermia (MH) susceptible patient should include drugs that do not trigger MH, while providing stress-free conditions. This case report describes a MH susceptible patient who was successfully induced and maintained with propofol for third molar extractions while under general anesthesia. Based on this case report, and the other relative few in the literature, it appears unlikely that propofol will trigger an episode of MH. Propofol provides the anesthetist with an alternative for inducing MH susceptible patients, but continued experience is necessary to document its safety and efficacy in these patients.
