Abstract
Background
The aim of this study was to evaluate the efficacy of intravenous infusion of clevidipine or esmolol for producing controlled hypotension during endoscopic repair of cerebrospinal fluid (CSF) rhinorrhea.
Patients and methods
Fifty adult ASA I and II patients scheduled for endoscopic repair of CSF rhinorrhea were randomized into one of two groups. Group C (25 patients) received clevidipine 0.5 mcg/kg/min increased by 0.5 mcg/kg/min every 3–5min to achieve the target mean arterial pressure (MAP) of 55–65mmHg. Group E (25 patients) received esmolol infusion 50 mcg/kg/min increased by 50 mcg/kg/min every 3–5min to achieve the target MAP. Surgical field Quality, blood loss, haemodynamic parameters, surgeons' satisfaction and adverse events were recorded.
Results
Time to reach target MAP was significantly shorter in group C compared to group E. Number of patients needed nitroglycerine was significantly higher in group E compared to group C (8 versus 2 respectively). The nitroglycerine dose needed/patient in group E was significantly more compared to group C. Surgeon satisfaction score was significantly higher in group C compared to group E. More patients in group E developed bradycardia compared to group C. Mean arterial pressure was significantly lower in group C compared to group E after 5 and 10 min from the start of the studied drugs infusion while it was significantly higher in group C after 25min from the start of the studied drugs. The heart rate (HR) was significantly lower in group E compared to group C 10min after starting drugs infusion till the end of surgery.
Conclusion
Both clevidipine and esmolol are effective for inducing controlled hypotension during endoscopic repair of CSF rhinorrhea. Clevidipine has the advantage of having shorter time to reach target MAP with less need of additional hypotensive agent and better surgeon satisfaction.
