Objective: Cesarean section is one of the most common operations. The new t
echnologies of postoperative pain treatment such as patient-controlled anal
gesia, are expensive and may limit women caring for their newborns shortly
after delivery. The present study assessed patient satisfaction with oral a
nalgesia following cesarean section. Study: design: An open prospective stu
dy was conducted on all women who had a cesarean section with epidural anal
gesia, during two consecutive periods of 3 months each. In the first group
of 109 women, an oral solution of I g dipyrone was allowed every 4 h, upon
patient request. Patients requesting additional analgesia were administered
a tablet of 30 mg immediate-release morphine sulfate. Tn the second group
of 90 women, the same protocol was used; however, oral morphine was the dru
g of choice and dipyrone was used for rescue analgesia. Pain intensity and
satisfaction were self-evaluated by patients using a visual analog scale. R
esults: The results of each study period were independently evaluated. The
demographic and obstetrical variables were similar in both groups. The dura
tion of analgesic effect of dipyrone was 6.5 h and the satisfaction score w
as 90. The duration of analgesic effect of oral morphine was 5.05 h and the
satisfaction score was 83.7. Overall, patients in both groups requested on
ly 25% of the permissible dosage of analgesia. Conclusions: Oral analgesia
following cesarean section provides satisfactory pain relief, is easily adm
inistered, and is a substantially less costly alternative to the new pain t
reatment technologies currently in use. (C) 2000 Elsevier Science Ireland L
