effect of Intrathecal Atropine to prevent Nausea & Vomiting after surgeries due to use Intrathecal Morphine in lower limb surgeries

Intrathecal morphine side effect is Nausea & Vomiting after surgery. aim of This clinical study was to evaluate the effect of intrathecal atropine on PONV in patients receiving intrathecal morphine in lower limb surgeries In this clinical trial, 120 patients undergoing lower limb surgery were randomly divided into 2 groups. Experimental group received0/1 mg (cc1) Intrathecal atropine and control group received 1cc saline 0/9%. PONV during the first 24 hours and hemodynamic changes in minute 3, 5, 10 and 15 after surgery in both groups were measured. Data were analyzed using SPSS software (verision14). independent t-test, repeated measures manova,and chi-square were used to compare comparison of variables. Hemodynamic cheanges before injection and 3, 5, 10 and 15 after injection in two groups was not significant (P>0/05). None of the patients in the intervention group were PONV, but 17 patients in the control group had PONV that this difference was statistically significant (p =0/000). Pain in the control group was great than intervention group while 26 patients in the control group and 14 patients in the intervention group had vas greater than 3 that this difference was statistically significant(P = 0/04). Intrathecal atropine without interfering Hemodynamic and pain relief prevent nausea and vomiting caused by Intrathecal morphine in patients undergoing surgery to the lower limbs.
