Abstract
A method of postoperative pain relief that promotes early infant and self-care activities by the mother after cesarean section allows more time to prepare the family for discharge and home self-care. The purpose of this study was to compare two known and practiced methods of postoperative pain relief following cesarean section. The research question asked was, is there a difference in post-operative pain relief in the first 24 hours after cesarean section in those receiving Conventional Intramuscular Analgesia (IM) and those receiving Patient Controlled Analgesia (PCA) using Meperidine as the analgesic, in relation to the level of pain, level of sedation, amount of narcotic administered, and respiratory rate? The study sample included 22 females undergoing cesarean section in a 300-bed hospital in a large metropolitan city in the midwest. The patients were randomly assigned to two treatment groups. Assessment of pain relief (analgesia) and sedation were made at four intervals for 24 hours. Concurrent assessments of amount of narcotic used, respiratory rate, and the presence of nausea and/or vomiting were made. The patients' reported ability to feed the infant was assessed, also. Data analysis was by Analysis of Variance for repeated measures. Data analysis for the reported level of pain measurements found the difference between analgesia groups to be statistically significant {p(..05). Subjects using PCA demonstrated a gradual reduction in the reported level of pain experienced during the first 24 hours after cesarean section. The data analysis for repeated measures of level of sedation, amount of narcotic used, and respiratory rate revealed that the differences between analgesia groups was not significant. However, there appeared to baa clinically significant difference in the amount of Meperidine administered, 230 milligrams versus 296 milligrams, for PCA and IM respectively. There was no difference between analgesia groups in the incidence of either nausea or vomiting or in the mother 1 s reported ability to feed the infant.
