Clinical Trial
Patient controlled intravenous analgesia (PCIA) in postoperative surgical patients: an audit.
We conducted an audit for the evaluation of the effectiveness, adverse effects and degree of patient satisfaction with Patient Controlled Intravenous Analgesia (PCIA) for postoperative pain control in surgical patients. ⋯ Patient controlled intravenous analgesia is an excellent method of postoperative pain relief, which provides a high degree of satisfaction to the patients.

Pain and sensory dysfunction 6 to 12 months after inguinal herniotomy.
Inguinal hernia repair is associated with a 5%-30% incidence of chronic pain, but the pathogenesis remains unknown. We therefore evaluated pain and sensory dysfunction by quantitative sensory testing 6-12 mo after open hemiorrhaphy. Before sensory testing, all patients (n = 72) completed a short-form McGill Pain Questionnaire and a functional impairment questionnaire. ⋯ Hypoesthesia, or tactile allodynia, in the incisional area was observed in 51% (37 of 72) of the patients, but the incidence did not differ significantly between the pain group and the nonpain group (14 of 20 versus 23 of 52; P > 0.3). We concluded that cutaneous hypoesthesia, or tactile allodynia, is common after inguinal hemiotomy but has a low specificity for chronic postherniotomy pain. Factors other than nerve damage may be involved in the development of chronic posthemiotomy pain.

Treatment of postsurgical pain is a major use of analgesics, particularly after abdominal surgery. Analgesics display a number of limiting side effects, including sedation, cognitive impairment, and ileus. Although several postoperative rodent models have been developed, these models do not address these concerns. ⋯ The current model is consistent with behavioral aspects of postoperative pain seen clinically. The effects of morphine and ketorolac alone and in combination were consistent with the reported analgesic efficacy and occurrence of side effects found with these agents clinically.
