[A comparison of patient-controlled epidural analgesia and intravenous fentanyl analgesia for laparoscopic ovarian cystectomy].
BACKGROUND
Laparoscopic ovarian cystectomy (LOC) can be performed in conjunction with patient-controlled epidural analgesia (PCEA) or intravenous fentanyl analgesia (IFA). Therefore, we evaluated the postoperative pain associated with both analgesia methods.


METHODS
We retrospectively evaluated the postoperative pain associated with PCEA and IEA. We calculated the combined remifentanil and fentanyl effect-site concentrations (ESC) in 43 patients at 1-2 hours after operations involving PCEA (n = 24, group E) or IFA (n = 19, group F). We also evaluated the supplementary analgesics required and the incidences of decreased respiratory rate and desaturation.


RESULTS
The patients' backgrounds were similar in both groups. The ESC was below 1.0 ng x ml(-1) in group E and 1.0-2.0 ng x ml(-1) in group F. In group E, five patients received supplementary local bolus injections, one received an NSAID, and one received a morphine injection, while four received NSAIDs and one received a morphine injection in group F. Thus, supplementary analgesics used for 7/24 patients in group E and 5/19 patients in group F (P = 1.000). No complications were noted in either group.


CONCLUSIONS
Both PCEA and IFA regimens can effectively manage postoperative pain with relatively low amounts of supplementary analgesics.
