ABSTRACT: The purpose of this study was to review incidence, indications, complications, and the anesthetic management of emergency obstetric hysterectomies.
This was a retrospective study of the cases of emergency obstetric hysterectomies performed at the Woman's Hospital over a 3 year period between January 2008 and December 2010. The indication for surgery, anesthetic management, operating time, estimated blood loss, pre- and postoperative hemoglobin and hematocrit values, need for blood transfusion, and perioperative complications were obtained.
During the study period there were 46 emergency obstetric hysterectomies for 20147 deliveries, giving an incidence of 2.28/1000 deliveries. The number of emergency hysterectomies was significantly higher with the cesarean deliveries than with the vaginal deliveries. The most common indication for emergency obstetric hysterectomy was placenta accreta. Postoperatively, Dissemimated Intravascular Coagulation (DIC) was the most common complication.
Abnormal placenta has been an main indication of emergency hysterectomy. Anesthesiologists should be eligible to aware of high risk of emergency hysterectomy and deal with massive hemorrhage.

ABSTRACT: Hypotension remains a common clinical problem of spinal anesthesia for cesarean delivery and phenylephrine is used as a vasopressor to address this. However, phenylephrine reduces maternal cardiac output (CO) due to reflex bradycardia. Glycopyrrolate is safe for the fetus, and increases heart rate (HR). Using a noninvasive measure of CO, we compared maternal hemodynamic changes between the phenylephrine only group (group P) and the phenylephrine plus glycopyrrolate group (group PG).
In this randomized study, 60 women scheduled for elective cesarean delivery were allocated to group P (n = 30) or group PG (n = 30). In both groups, phenylephrine was infused at 50 µg/min. This infusions stopped if systolic blood pressure (SBP) was higher than the baseline value, and phenylephrine 100 µg was injected if SBP was lower than 80% of the baseline value from spinal anesthesia to delivery. In group PG, glycopyrrolate 0.2 mg was injected intravenously after spinal anesthesia. Hemodynamic parameters, such as SBP, heart rate (HR), stroke volume index (SVI), cardiac index (CI) were measured before and until 15 min after spinal anesthesia.
There were no significant differences in SBP and SVI compared to the baseline value in each group and between the two groups. HR and CI reduced significantly from 8 min to 15 min in group P compared to the baseline value as well as group PG for each time-point. However, HR and CI were maintained in group PG.
The use of glycopyrrolate added to phenylephrine infusion to prevent hypotension by spinal anesthesia for cesarean delivery was effective in maintaining HR and CI.

ABSTRACT: This study was conducted to compare the efficacy of a combination of ondansetron and dexamethasone with that of metoclopramide and dexamethasone for prevention of postoperative nausea and vomiting (PONV) in gynecologic patients receiving fentanyl IV-patient controlled analgesia.
One hundred patients were divided into two groups at random. In Group O, 5 mg of dexamethsone was administered after tracheal intubation, while 4 mg of ondansetron was administered at the end of surgery. In Group M, 5 mg of dexamethsone was administered after tracheal intubation and 20 mg metoclopromide was administered at the end of surgery. During the experiment, the PONV was evaluated at regular intervals. In addition, the incidence of nausea, and vomiting and the numerical rating scale (NRS) of nausea was measured (range, 0-10).
The overall incidence of PONV in Group O was 22/50 (44%) while that in Group M was 19/50 (38%). There were no significant differences in the incidence of nausea, moderate to severe nausea (NRS of nausea, 4-10), or vomiting between groups.
Treatment with a combination of 20 mg metoclopramide and 5 mg dexamethasone is an effective, safe, and inexpensive way to prevent PONV when compared to treatment with 4 mg ondansetron and 5 mg dexamethasone.
