تأثیر استفاده از مانیتورینگ شاخص دوطیفی (Bispectral index (BIS)) بر ریکاوری و عوارض بعد از عمل در بیماران تحت عمل جراحی سزارین

Background and Aim: Anesthesia has several side effects which are different based on the type of surgery, medication, and depth of anesthesia. The present study aimed at identifying the effect of bi-spectral index monitoring on recovery and postoperative complications in caesarean. Materials and Methods: In this double-blinded clinical trial study with control group, 68 women who were candidates for caesarean were selected using available sampling method and were then randomly assigned in to two groups. For the control group, anesthetic maintenance drug was prescribed based on every body’s weight and hemodynamic conditions while intervention group received titrated dose of anesthetic maintenance drug as needed for maintaining bi-spectral index between 40 and 60. Data collection tool.included a researcher-designed checklist in which the time of extubation after surgery, discharge from the recovery unit (based on Aldert benchmark), and complications during recovery were recorded in addition to demographic data. The obtained data was analyzed by SPSSsoftware(V:16) using statistical independent T test, as well as Fisher Exact test. at the significant level of P<0.05. Results: Mean time of extubation was 7.76 ±3.12 in the control group and 3.59 ± 1.04 minutes in the intervention group (P<0.001). Mean time of discharge from recovery ward was 18.06 ± 5.92 in the control and 11.55 ±4.39 minutes in the intervention group (P<0.001). The incidence of postoperative recovery complications didn’t show any significant difference in the two groups (P>0.05). Conclusion: Bi-spectral indicator, as a monitoring of the depth of anesthesia in caesarean section, speeds up the extubation time, discharge from recovery, and mothers' consciousness to care their babies.
