Title

THE EFFECT OF ORAL CLONIDINE PREMEDICATION ON HEMODYNAMIC RESPONSES DURING GYNECOLOGIC LAPARASCOPY UNDER GENERAL ANESTHESIA

Pages

  39-46

Abstract

 Background & Aim: CLONIDINE, an alpha 2 agonist, attenuates sympathetic responses during general anesthesia and improves the intra-operative hemodynamic stability. In this randomized double blinded clinical trial study, we report the effects of 300 μg oral CLONIDINE premedication (n=22) or placebo (n=22) on hemodynamic alteration during gynecologic laparoscopic surgery, under general anesthesia. Previous works have reported the effectiveness of CLONIDINE on blunting the sympathetic responses during open surgeries.Patients & Methods: Anesthesia consisted of isoflurane/O2 and REMIFENTANIL. Muscle relaxation was maintained by cisatracurium. Hemodynamic data were obtained at 5 epochs: base, after induction of anesthesia, insufflation (after peumoperitoneum, supine position), trendelenburg 30 degrees, and end (after supine extubation.Results: There was a significant increase in systolic blood pressure during peritoneal insufflation and trendelenburg position in patients in the control group (129±23, 115±29 mmhg) compared with patients in the CLONIDINE group(126±34, 116±25 mmhg), P<0.05. Peritoneal insufflation and trendelenburg positioning resulted in significant increase in systolic blood pressure compared with base, in patients in both groups (control 127±15 mmhg to 129±23 & 126±34 mmhg; CLONIDINE 109±19mmhg to 115±29 & 116±25 mmhg, P<0.05). After extubation, there was significant increase in diastolic BP in CLONIDINE group: (98±32 mmhg vs 86±8mmhg in control group). During LAPAROSCOPY, there was a significant increase in diastolic BP in the control group (89±16 mmhg vs 75±18 mmhg in CLONIDINE group; P<0.05). There was a significant increase in diastolic BP in the patients in CLONIDINE group (98±32) compared with the patients in control group (86±8) P<0.05. There was significant slower HR during the procedure in both groups (71±29 bpm, 63±22 vs base 85±22bpm, 85±39).Conclusion: It seems that CLONIDINE can not blunt the hemodynamic responses in hyperdynamic phases after gynecologic LAPAROSCOPY in spite of its effectiveness during the procedure.
