Abstract
Introduction:Nerve block is a technique whereby local anesthetic solutions are infiltrated around a nerve (or perineurally) to provide anesthesia and analgesia. Nerve block for intraoperative and postoperative pain management is associated with improved analgesia, fewer opioid-related adverse events, earlier ambulation and shorter hospital stay when compared with intravenous opioid analgesia alone Patients and Methods Setting: The study was conducted in accordance with the ethical committee protocols and informed consent procedures of Ain-Shams University Maternity Hospital during the period between Augusts to December 2016 Sample size calculation: Sample size was calculated using PASS® version 11 programs, setting the type-1 error (α) at 0.05 and the power (1-β) at 0.8. Results from a previous study showed that the mean duration of time before the first analgesic administration (Duration of analgesia), was 332 ±17 minutes among combined group while among placebo group it was 228.4 ±41minutes with mean effect size of 103.6 Calculation according to these values produced a minimal sample size of 20 cases in each group. Results. Conclusion: Para cervical block could be used as a safe and effective anesthetic technique in patients who need surgical uterine evacuation of missed abortion. Adding dexamethasone could increase effectiveness and duration of Para cervical block. Intraoperative pain level was accepted in 80 % of patients, these patients had no or mild to moderate accepted pain. We did not report any postoperative complications in our patients including (excessive vaginal bleeding, hematoma or general manifestations of lidocaine toxicity).
