PREOPERATIVE ORAL CODEINE EFFECT ON POSTOPERATIVE CAUGH CONTROL IN CATARACT SURGERY
Abstract
Introduction: cataract surgery is .one of the most common operation in ophthalmology. Post operative caught can lead to anterior chamber hemmorage and dehiscence of suture so we were going to finding a way to overcome to this problem.
Method: This study is a clinical trial one which was done on 150 ASA 1, 2 patient that were over 45 years old age. These patient have cataract surgery under GA in Farabi Hospital of Esfahan medical university. All of the patient were intubated under direct laryngoscopy. Patients that have more of one laryngoscope, difficult intubation, thraceal intubation prolonged more than 15 seconds and those which have opiate addiction. We divided the patients into two 75 patient group by randomized selection.
This study is double blind and 30mg codeine phosphate and placebo has given to the patient one hour preoperatively. Heart rate and systolic and diastolic, blood pressure has been recorded preoperatively, three minutes after intubation and three minutes after extubation respectively. Caught has been counted and recorded immediately. Five minutes and 30 minutes after extubation and results in contorol group are compared with the results in another group.
Discussion: According to the statistical analysis t-student test, chi-square and non parametric test and Pvalue only changes in heart rate after extubation has been different in two groups and other findings make no difference in two groups. There was not any significant difference between two groups about age, sex, duration of surgery, preoperative mean heart rate and blood pressure. There was not any difference about mean number of coughs between two groups and according to this study oral codeine phosphate has administered preoperatively has not any effect on reducing postoperative caught in patients who have GA and tracheal incubation for cataract surgery.
