The Bispectral Index Interest during General Anesthesia at the University Hospital of Parakou (Republic of Benin) in 2019

Background: The bispectral index (BIS) derived from the electroencephalogram is an additional means of monitoring the depth of narcosis. Objective: To compare the monitoring of the depth of narcosis by the BIS associated with clinical data versus standard monitoring at the University Hospital of Parakou in Benin in 2019. Methods: This was an observational study for descriptive and analytical purposes with prospective data collection, carried out in general surgery and intensive care unit for 4 months. The inclusion criteria were: an age ≥ 18 years, an ASA score ≤ 3, surgery under general anesthesia and informed consent of the patient. Two groups were formed: non-BIS group monitored by clinical parameters (PA, FC, FR, EtCO2, and SpO2) only and BIS group monitored by bispectral index in addition to clinical parameters. Patients were seen 48 hours after the procedure. Results: 36 patients were collected. The mean age was 40.63 ± 16.77 years with a sex ratio of 3. ASA 1 patients represented 86.11% of the sample and ASA2 patients 13.89%. The average doses of Propofol were not significantly reduced in the BIS group (p = 0.555). On the other hand, the period of intraoperative recovery (p-value = 0.007) and the NVPO (p = 0.043;OR = 0.10;95% CI [0.01 - 0.97]) were significantly reduced by the use of BIS. One case of intraoperative memorization (2.78%) was however found in the BIS group. Conclusion: The bispectral index makes it possible to significantly reduce the risk of intraoperative awakening and PONV, and not significantly reduce the consumption of Propofol.

Perioperative Materno-Fetal Morbimortality Related to the Caesarean in the Hospital Setting in Mali

Introduction: During childbirth by Caesarean, several types of anesthesia can be used. The Caesarean, the most practiced surgical delivery technique in obstetrics, has a risk for complications for both the pregnant women and newborns. Objective: To evaluate the importance of the complications due to Caesarean in the Teaching hospital Gabriel Toure. Patient and Methods: We conducted a cross sectional survey in the departments of intensive care unit and gyneco-obstetric from January to August 2017 in the University hospital Gabriel Touré of Bamako. Our study population was pregnant women who gave birth to children by Caesarean. We included all cases of preventive and emergent Caesarean under loco-regional or general anesthesia. Data were compiled from the obstetrical files of the patients, the anesthetic consultation registry and the databasis of the department of gyneco-obstetric. The test of khi2 of Pearson was used for the comparison of our results with a value of p < 0.05 considered as statistically significant. The consent of the patients or parents was gotten. The survey didn’t include a potentially dangerous act. Results: During the study period, 1875 childbirths have been recorded of which 633 were by Caesarean (33.7%). We collected and analyzed 524 files of Caesarean. The mortality rate was 1.5% in pregnant women and 15% in newborns. The average age was 26.6 ± 6.9 ans. Pregnant women were referrals in 59.4% of the cases. The most frequent motive of referrals was high blood pressure and pregnancy in 66.6%. The Caesarean was indicated in most of the cases on previously operated uterus in 22% and eclampsia was present in 14%. The maternal mortality had occurred in a context of hemorrhage in 50% of the cases. The factors of maternal morbi-mortality were the mode of admission, iterative Caesarean, t surgeon, context of the Caesarean, realization of the anesthetic consultation and the technic of anesthesia (p = 0.05). The factors of fetal mortality were the realization of endo-tracheal intubation, technic of anesthesia, realization of the anesthesia consultation, context of the Caesarean, iterative Caesarean and the mode of admission (p ≤ 0.05). Conclusion: The caesarean is associated with a high risk of maternal complications and a very important fetal mortality. The anesthesia consultation in the follow-up of pregnancy would reduce this high mortality.
