Anesthesia Results
Table 9  refers to anesthesia data overall and by color code used. 533 (66.7%) patients had epidural analgesia before the cesarean section.  There was no significant difference in the number of conversions to general anesthesia based on the color code used. Lack of analgesia was the main reason for conversion to general anesthesia (61 patients, i.e. 85.9%). Four patients received general anesthesia due to hemodynamic instability during cesarean section (occurrence of a vascular injury). Four patients developed a complication of epidural anesthesia requiring general anesthesia. Two patients underwent general anesthesia after failure of épidural anesthesia.
