Cesarean is one of the most common surgeries. Pain is on of it`s side effect which bothers mothers.Opioids are the most common pain relief which used as Intra muscular, Intra venues, sub cotaneous or new methods such as patient control analgesia (PCA). As it is new method, research decided to compare efficacy of these 2 methods. This is a prospective clinical trial study which has done on primi parous with full term, single pregnancy who were candidate for elective cesarean in Sepahan shahr hospital of Isfahan in year 2010. Excluding criteria was using another drugs, essential disease, not to permit, dizziness, coma. Number of cases was 44 in each group which had been selected simple. In recovery and surgery ward patients were evaluated about vital signs- drugs side effects in 1, 2, 4, 8, 12 hours after surgery. Pain score evaluated by visual analog scale (VAS) by patients. Satisfaction of pain relief asked from patients. Petidin was significantly more effective for pain relief than PCA in1, 8, 12 hours after surgery (P < 0.05). Mean of pain was less in 2,4hours after surgery in Petidin Im group than PCA but not meaningful. Total Petidin was more effective than PCA for pain relief (P < 0.02). This study showed although PCA is new method for pain relief but it is doesnt have efficacy such as old methods such as Intra muscular petidine. Also patient`s satisfaction was less in PCA method. It may because of expensive and it`s side effect such as nausea and vomiting.
