[Influence of various premedication agents, inhalation anesthetics and adjuvants on anesthesia with an opioid, alfentanyl].

Alfentanil mask anaesthesia was performed in 63 patients undergoing termination of pregnancy or curettage. Three different types of premedication were used: a) pethidine, promethazine, and atropine; b) diazepam and atropine; c) atropine. The patients were ventilated either with nitrous oxide and oxygen or with halothane and oxygen. Halothane reduced the frequency of muscular rigidity (32%; N2O 75%), postoperative sickness, and vomiting (23%; N2O 50%). On the other hand, patients regained consciousness earlier if nitrous oxide was used. Premedication a) also reduced the frequency of nausea and emesis (21%; other premedications 63%).-Alfentanil intubation anaesthesia was performed in 52 patients undergoing laparoscopy. Premedication and inhalation anaesthetic varied as described above in the group with mask anaesthesia. Muscular rigidity did not occur, and nausea/emesis were rare events (8%). Halothane prolonged the recovery phase of consciousness and respiration. Premedication a) also resulted in respiratory depression.

Comparison of adjuvant anesthetics for propofol induction.

PURPOSE: Fentanyl was compared with nitrous oxide/sevoflurane as an adjuvant anesthesia to propofol during induction. METHODS: Two-hundred sixty-three patients of American Society of Anesthesiologists physical status 1 or 2 undergoing minor surgery were randomly divided into two groups. Group F patients (n = 125) received 2 microg x kg(-1) fentanyl and 1.8 mg x kg(-1) propofol, and were ventilated by mask with oxygen. Group S patients (n = 138) received 1.8 mg x kg(-1) propofol, followed by inhalation of 4% sevoflurane in N2O (41 x min(-1)) and oxygen (21 min(-1)) by mask. The trachea was intubated exactly 2, 3, 4, or 5 min after injection of 0.1 mg x kg(-1) vecuronium, and the conditions of endotracheal intubation were scored according to the patients' responses to laryngoscopy and endotracheal intubation. Systolic blood pressure (SBP) and heart rate (HR) were measured before and after endotracheal intubation. The cost of anesthetics was also calculated. RESULTS: No significant differences in SBP were observed between the groups throughout the induction period. HR did not change from preanesthetic values in group F. In contrast, HR in group S patients increased by 9-18 beats x min(-1) (bpm) after inhalation of N2O/sevoflurane and further increased by 17-21 bpm following endotracheal intubation. Significant differences in HR were noticed between the groups (P < 0.001). The conditions of endotracheal intubation were similar in the two groups and were satisfactory when mask ventilation exceeded 3 min. Fentanyl was less expensive than sevoflurane/N2O anesthesia when mask ventilation exceeded 3 min. CONCLUSION: From the standpoints of hemodynamics and drug cost, fentanyl is preferable to N2O/sevoflurane inhalation as an adjuvant to propofol during induction, because mask ventilation for more than 3 min was required for satisfactory endotracheal intubation.
