ObjectivesThe aim of this study is to examine the effects of sufentanil added to low-dose hyperbaric bupivacaine in unilateral spinal anaesthesia for outpatients undergoing knee arthroscopy.MethodsSixty two patients (ASA I-II) aged 20 to 50 who were planning on undergoing a knee arthroscopy were enrolled in this study. Patients were randomly divided into two groups. Unilateral spinal anaesthesia with 1ml 0.5% hyperbaric bupivacaine was administered to Group B (n=33); and unilateral spinal anaesthesia with 0.5ml (2.5µg) sufentanil added to 1ml hyperbaric bupivacaine was administered to Group BS (n=29).ResultsThere were no statistically significant differences observed between the groups in terms of demographic data, hemodynamic parameters, maximum sensorial, sympathetic and motor block levels, time to motor block resolution, and time of discharge (p>0.05). There were statistically significant differences between the groups in terms of two segments regression time (Group B=52 min., Group BS=59 min.), ambulation time (Group B=147 min., Group BS=157 min.) and urination time (Group B=136 min., Group BS=149 min.) (p<0.05). In this study, no itching was observed in Group B, whereas seven patients in Group BS were observed as having postoperative itching (p<0.05).ConclusionAll patients were successfully given unilateral spinal anaesthesia with sufentanil added to low-dose hyperbaric bupivacaine for an outpatient knee arthroscopy, without affecting the time of discharge. However, for one-day interventions such as arthroscopy, it was concluded that administration of only low-dose hyperbaric bupivacaine was sufficient.
