Comparative StudyA comparison of labetalol, acebutolol, and lidocaine for controlling the cardiovascular responses to endotracheal intubation for oral surgical procedures.
Arterial blood pressure and pulse rate changes following tracheal intubation were studied in 80 patients undergoing oral surgical procedures who received an etomidate/suxamethonium anesthetic induction sequence. Three treatment groups and a control group were used. ⋯ A pre-induction dose of labetalol was found to be more effective than acebutolol and lidocaine in attenuating the pressor response to instrumentation and intubation. Labetalol should prove most useful for those patients at risk from the transient hypertension and tachycardia following instrumentation and intubation.

Case ReportsRhabdomyolysis and acute renal failure following use of succinylcholine and enflurane: report of a case.
A case of succinylcholine and enflurane induced rhabdomyolysis and myoglobinuric acute renal failure in a mentally retarded patient is presented. The report illustrates some principles of management and the correlation of laboratory findings with the syndrome. When using general anesthesia in mentally retarded patients it is recommended that: 1) a careful personal and family past anesthetic history be taken; 2) drugs and apparatus for treatment of the crisis be available before anesthesia is induced; 3) the use of succinylcholine and potent inhalation anesthetic agents be avoided; 4) there is early diagnosis by prompt recognition of the clinical signs; and 5) that body temperature monitoring and frequent observation of vital signs during and after an operation be carried out.

Case ReportsBilateral fixation of a nasotracheal tube by transfacial Kirschner wires.
Because of the high margin for error with transfacial internal wire fixation, even in the hands of an experienced practitioner, alternative modalities in the treatment of zygomaticomaxillary complex fractures should be considered. When the use of transfacial rigid wire fixation is indicated, emphasis should be placed on prevention and early recognition of nasotracheal transfixation to avoid unnecessary postoperative catastrophies.

Randomized Controlled Trial Clinical TrialEffect of pretreatment with acetaminophen-propoxyphene for oral surgery pain.
To determine the effect of pretreatment and multiple doses on postsurgical pain, a study of the relative analgesic efficacy of placebo, acetaminophen 650 mg, and propoxyphene napsylate 100 mg alone and in combination was conducted. Forty-five patients undergoing surgical removal of impacted third molar teeth under local anesthesia were randomly allocated to the four treatment regimens under double-blind conditions. The first oral dose was administered one hour preoperatively and the second dose when the pain became moderate or severe, following the dissipation of the local anesthesia. ⋯ Duration of analgesia was also significantly longer with both propoxyphene-containing treatments. No side effects were reported. The results suggest that pretreatment with a narcotic agonist markedly improves postoperative analgesia.
