A total of 110 patients undergoing elective abdominal hysterectomy were anesthetized in random order with either isoflurane in nitrous oxide and oxygen or isoflurane in air and oxygen. Fentanyl was used as an adjunct to isoflurane in all patients, 0.05 mg every 45 min. No difference was found between the two anesthetic techniques in the incidence of nausea, vomiting, or both during the first 24 hr after operation. The overall incidence was 62 and 67% for air-O2 and N2O-O2 groups, respectively. Patients who had had nausea or vomiting after previous anesthetics had nausea or vomiting significantly more frequently than patients who did not. It is concluded that nitrous oxide does not contribute to the occurrence of nausea or vomiting after isoflurane anesthesia for gynecologic laparotomies.

Resuscitation report-forms of the Surf Life-Saving Association of Australia, for the period 1973-1983, were analysed. During this period there were 262 immersion victims at beaches that were patrolled by life-savers. Of these, 162 victims survived, some of whom received expired-air resuscitation (n = 61) or cardiopulmonary resuscitation (n = 29). Among those who drowned, none was younger than five years of age. Vomiting and regurgitation were major problems during resuscitation. Respiratory and cardiopulmonary arrest occurred after apparently-successful rescue; this highlights the necessity for the close observation of victims and the early administration of oxygen to all immersion victims. Resuscitation in deep water has been shown to be effective, and instruction in these techniques is now standard teaching within the Surf Life-Saving Association of Australia.

Propofol is an intravenous anesthetic currently available for clinical investigative use. The intraoperative and postoperative effects of propofol were compared to methohexital when used as an adjuvant to nitrous oxide for outpatient anesthesia. Sixty healthy young women were randomly assigned to receive either methohexital, 1.5 mg/kg intravenously (IV), or propofol, 2.5 mg/kg IV, for induction of anesthesia. Both drugs produced transient cardiovascular and respiratory depression after induction. Maintenance of anesthesia consisted of either methohexital, 6 +/- 2 mg/min, or propofol, 7 +/- 2 mg/min (mean +/- SD) by continuous infusion in combination with nitrous oxide, 70% in oxygen. Use of a propofol infusion was associated with lower blood pressures and heart rates during maintenance. Propofol was associated with fewer side effects (e.g., hiccoughing, nausea, and vomiting) intra- and postoperatively. Recovery times for awakening, orientation, and ambulation were consistently shorter with propofol. We conclude that propofol is a useful alternative to methohexital for induction and maintenance of outpatient anesthesia.

The effectiveness of 50 mg cyclizine and 2.5 mg perphenazine against the emetic sequelae of 100 mg meptazinol were studied in a randomized double-blind placebo-controlled trial. Three groups of 40 women received the opioid, together with an anti-emetic by i.m. injection, as premedication prior to minor gynaecological surgery. Beneficial or noxious effects were noted at standard time intervals and anaesthesia standardized as incremental methohexitone with nitrous oxide/oxygen. In the placebo group, 33 out of 40 subjects experienced either nausea or vomiting at some time after the opioid. Cyclizine, 50 mg, provided significant reduction of emetic tendency in both pre-operative and post-operative phases of the study with 22 out of 40 subjects experiencing nausea or vomiting overall. Perphenazine, 2.5 mg, showed no useful anti-emetic effect. Both anti-emetics increased the soporific effect of premedication at the 90-min interval. Subjects receiving perphenazine experienced significantly more dizziness than those of other groups.

The usefulness of intra-operative antiemetics and postoperative oral fluid restriction in the prevention of vomiting following anaesthesia for ophthalmic surgery, was studied in 200 patients. They were allocated into four groups of 50 and given either saline (as control), droperidol, metoclopramide or prochlorperazine. Oral intake was restricted postoperatively in half of the patients of each group. Anaesthesia comprised morphine and atropine premedication and a halothane, nitrous oxide and oxygen spontaneous breathing technique. No significant beneficial effects resulted from intra-operative antiemetics; vomiting incidences of 26% after saline and droperidol, 28% after metoclopramide and 14% after prochlorperazine were observed. Younger patients and females vomited most frequently. Restriction of oral fluids did not decrease the incidence of vomiting but demonstrated that approximately half of those patients who vomit do so with their first postoperative oral intake. Vomiting was observed more frequently after non intra-ocular surgery than after intra-ocular surgery (37% cf. 16%, p less than 0.01) and postoperative analgesics were required by more non intra-ocular patients than by intra-ocular patients (25% cf. 5%, p less than 0.001). Squint patients vomited most frequently (48%) and most frequently required postoperative analgesia (35%).

Cardiorespiratory function in 42 patients admitted to the Regional Poisoning Treatment Centre, Edinburgh who underwent gastric lavage for self poisoning, was studied using an electrocardiograph and an ear oximeter. Mean pulse rate rose from 92 to 121 beats per min and the mean partial pressure of oxygen fell from 95 to 80 mmHg during lavage (P less than 0.001). These changes were significantly greater in conscious than unconscious patients, in smokers than in non-smokers and most marked in male smokers aged 45 or older. No sex or age differences were noted. Electrocardiograph changes were noted in 41% of patients, including potentially serious changes in 2 patients. The indications for gastric lavage should probably be reviewed particularly in conscious older patients who smoke and due consideration given to induced emesis and ingestion of activated charcoal as alternatives.

Etomidate, a nonnarcotic, nonbarbiturate hypnotic agent, was assessed in a group of 20 patients requiring general anesthesia for outpatient oral surgical procedures. Changes in mean blood pressure, heart rate, and transcutaneous oxygen tension (PtcO2) were examined following the intravenous administration of etomidate for the induction and maintenance of general anesthesia. Clinical evidence of pain on injection, myoclonic muscle activity, apnea, nausea, and emesis were documented. A postoperative questionnaire evaluated levels of amnesia and acceptance of the drug by the patient and surgeon. No significant (P less than 0.05) change in PtcO2 occurred during etomidate infusion; however, a statistically significant but clinically insignificant change did occur in mean blood pressure and heart rate. Although myoclonic muscle activity, pain on injection, and nausea and vomiting were documented, the subjective evaluation of this agent by patient and surgeon was favorable.

In 73 unpremedicated patients scheduled for minor outpatient oral surgery or restorative dentistry, enflurane anaesthesia was induced either with an emulsion formulation of propofol (2.5 mg/kg) or with methohexitone (2 mg/kg). Sensations at the site of the injection were more common when the drugs were injected into a vein in the dorsum of the hand (58% for propofol and 28% for methohexitone) when compared to a vein in the forearm or antecubital area (7 to 8% with sensations). After induction of anaesthesia intravenous suxamethonium was given, and endotracheal intubation carried out. Anaesthesia was subsequently maintained using nitrous oxide, oxygen and enflurane. One minute after intubation a similar decrease in mean systolic arterial pressure was noted in both groups but the increase in mean heart rate observed in the methohexitone group (22 beats/min) was significantly (P less than 0.01) greater than that seen in the propofol group (11 beats/min). Excitatory side effects were observed in only one patient in the propofol group and in 12 patients in the methohexitone group (P less than 0.01 between groups). Walking and perceptual speed tests of recovery showed transient impairment of psychomotor skills for 30 to 60 min after both anaesthetic regimens. The incidence of nausea or vomiting was similar (27 to 33%) in both groups. It is concluded that both propofol in emulsion form and methohexitone are satisfactory induction agents in outpatient dentistry. Propofol provided a smoother induction of anaesthesia and recovery was as rapid as after anaesthesia induced with methohexitone.

The clinical and physiologic features of 28 infants with Pierre Robin syndrome and those of 20 infants with various types of nasal obstruction were reviewed to determine whether different causes of upper airway obstructure may lead to a common syndrome. The patients had no significant differences in distribution of main clinical manifestations. Their features included cyanosis with respiratory distress, apneic spells, oropharyngeal dysphagia, vomiting, failure to thrive, cor pulmonale, brain damage, and sudden death during sleep. The common physiologic manifestation appeared to be an oropharyngeal obstruction caused by glossoptosis, which occurred mainly during wakefulness. Upper airway obstruction led to hypoxemia, which, in many instances, was not associated with hypercapnia and was not relieved by oxygen administration. It is concluded that regardless of a specific cause, any airway obstruction that results in a decreased inspiratory pressure overcoming the airway maintaining genioglossus action causes a glossoptosis-apnea syndrome.

Compound LY175326 is one of a series of novel cardiovascular agents with both inotropic and vasodilator activities. In cat papillary muscles, LY175326 increased contractility in a concentration-dependent manner; these actions were not blocked by prazosin, propranolol or cimetidine. Inotropic responses were observed in unpaced, perfused guinea-pig hearts and these effects were associated with modest increases in heart rate and coronary flow. An i.v. dose of 0.1 mg/kg of LY175326 caused 54 and 95% increases in contractility in either the anesthetized cat or dog, respectively; corresponding heart rates were increased by less than 10%. Oral administration of 0.5 mg/kg to dogs was associated with an inotropic response that was maximal between 60 and 90 min and lasted in excess of 3 hr. These effects were not accompanied by increases in heart rate, gross behavioral changes or emesis. The pharmacology of LY175326 was evaluated in a propranolol-induced heart failure model using anesthetized beagle dogs. A bolus injection of 0.15 mg/kg of LY175326 followed by an infusion of 0.4 mg/kg/hr reversed the hemodynamic symptoms of heart failure by increasing left ventricular dP/dt60, cardiac output and stroke volume and reducing left atrial filling pressure and vascular resistance; heart rate was unchanged and calculated myocardial oxygen consumption was reduced. This balance of inotropic:vasodilator activities may provide a means of improving cardiac function while maintaining the myocardial oxygen supply:demand.
