In terms of pain scores, epidural analgesia is superior to that provided by IV remifentanil. However, there was no difference in the pain relief scores between the treatments.
We determined the minimum effective dose of patient-controlled IV remifentanil for labor analgesia. There was wide individual variation in the dose required for effective labor analgesia. Potentially serious side effects, which were observed frequently during remifentanil analgesia, may limit its use in obstetrics.
Thirty-two patients participated in a study to compare the use of an ultrasonically activated scalpel (Harmonic scalpel) for tonsillectomy on one side and a blunt dissection tonsillectomy on the other. Pain scores at rest and on swallowing expressed as the area under curves (AUC) during the 10 h after surgery, intra-operative blood loss and the need for electrocoagulation for haemostasis were significantly higher on the blunt dissection side than on the Harmonic scalpel side (p < 0.05). However, pain scores expressed as AUC at rest, on swallowing, the day's least, average and worst levels of pain, and the day's worst otalgia during the second week after surgery were significantly higher on the Harmonic scalpel side than on the blunt dissection side. In conclusion, we found that Harmonic scalpel tonsillectomy was associated with decreased severity in pharyngeal pain on the day of the operation but increased pharyngeal pain and otalgia during the second postoperative week.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
