ABSTRACT
Sixty healthy patients undergoing elective short surgery under general anaesthesia were randomly allocated into two groups: Group A: receive a mixture of neostigmine 1.5 mg and atropine 1 mg to anatagonize the residual muscle relaxant. Group B: spontaneous recovery was allowed. The incidence of past-operative vomiting was assessed. There were no significant difference in frequency of nausea and vomiting between the two groups. The incidence of postoperative nausea was 22 in group A and 28 in group B, while vomiting was 14 in group A and 18 in group B.These results ensuring a decreased incidence of postoperative nausea and vomiting after antagonizing residual neuromuscular block by neostigmine and atropine, enable smooth recovery and early discharge from the hospital especially in day-case surgery
