A combination of alfentanil-lidocaine-propofol provides better intubating conditions than fentanyl-lidocaine-propofol in the absence of muscle relaxants.

PURPOSE: To compare the ease of tracheal intubation without the use of muscle relaxants following an alfentanil-lidocaine-propofol sequence vs a fentanyl-lidocaine-propofol sequence. CLINICAL FEATURES: In 80 ASA I and II adult patients undergoing elective laparoscopic surgery, we compared the intubating conditions following alfentanil 20 microg x kg(-1), lidocaine 1.5 mg x kg(-1), propofol 3 mg x kg(-1) (Group I; n = 40) vs fentanyl 2 microg x kg(-1), lidocaine 1.5 mg x kg(-1), propofol 3 mg x kg(-1) (Group II; n = 40). The intubating conditions were scored by jaw relaxation, vocal cord position and response to intubation, as well as by blood pressure and heart rate changes. The intubating conditions were good or excellent in 95% of patients in Group I vs 62.5% of patients in Group II (P < 0.05). Blood pressure decreased from a preinduction value of 86 +/- 13 mmHg to 72 +/- 28 mmHg and 74 +/- 19 mmHg in Group I, and from 85 +/- 12 mmHg to 78 +/- 15 mmHg and 78 +/- 12 mmHg in Group II, one and five minutes following intubation (P < 0.05). This drop in blood pressure was not different between the two groups. CONCLUSION: An alfentanil-lidocaine-propofol sequence offers significantly better intubating conditions than a fentanyl-lidocaine-propofol sequence in healthy adult patients.

Amniotic fluid embolus: can we affect the outcome?

PURPOSE OF REVIEW: Amniotic fluid embolism is a rare catastrophe unique to pregnancy. Its mortality rate remains high despite efforts at prompt and aggressive management protocols, highlighting the need to maintain a high index of suspicion. RECENT FINDINGS: The intrusion of amniotic fluid into the maternal bloodstream may lead in certain women to a complex series of physiological reactions mimicking those seen in human anaphylaxis or sepsis, negating the purely embolic phenomenon theory as previously understood. The clinical picture is the sudden onset of cardiovascular collapse, cyanosis, haemorrhage or disseminated intravascular coagulopathy, during or soon after delivery. SUMMARY: The mainstay of a successful outcome remains the identification of high-risk patients, as well as early clinical diagnosis and management.

Intraperitoneal and intravenous routes for pain relief in laparoscopic cholecystectomy.

BACKGROUND: Postoperative abdominal and shoulder pain are the most common complaints after elective laparoscopic cholecystectomy. Postoperative pain is multifactorial in origin, and therefore multimodal therapy may be needed to optimize pain relief. METHODS: We conducted a double-blind study where patients were randomly allocated to 1 of 5 groups of 20 patients each. Statistical significance was considered P<0.05. Group 1 received 40 mL bupivacaine 0.25% intraperitoneal spray. Group 2 received 40 mL bupivacaine 0.25% intraperitoneal spray mixed with 200 mg ketoprofen. Group 3 received 40 mL bupivacaine 0.25% intraperitoneal spray and intravenous 200 mg ketoprofen. Group 4 received 200 mg ketoprofen intravenously. Group 5 was the control group. RESULTS: Demographic data were similar in the 5 groups. As compared with the control group, group 1 had significantly lower abdominal pain scores at 6 hours; group 2 at 0, 1, 2, and 6 hours; group 3 at 0, 1, 2, 6, 12, and 24 hours; and group 4 at 2 hours. Group 1 had significantly lower shoulder pain scores at 1 and 6 hours; group 2 at 0 and 6 hours; and groups 3 and 4 at 0, 1, and 6 hours. The number of patients requiring postoperative rescue analgesics and the incidence of postoperative vomiting were significantly lower in group 3 only. CONCLUSIONS: A multimodal approach to pain management following elective laparoscopic cholecystectomy is best achieved with a combination of 40 mL bupivacaine 0.25% intraperitoneal spray and 200 mg intravenous ketoprofen, achieving the least incidence of postoperative vomiting.
