Sedation and Analgesia Using PFK Versus General Anesthesia in Urological Procedures

Patients were anesthetized using Fentanyl (2 mcg per kg) and Propofol (1-2 mg per kg). Proper classic laryngeal mask airway was inserted afterwards.

A mixture of 5 mcg/ml of Fentanyl, 5 mg/ml of Propofol, and 5 mg/ml of Ketamine was used. Each patient received an initial dose of 0.5 mg/kg from the solution, then after waiting for 60 seconds, another 0.5 mg/kg were given. Maintenance was given as boluses of 0.2- 0.33 mg/kg every three to five minutes. No Laryngeal mask airway nor endotracheal tube were inserted, and the patients were breathing spontaneously through a simple face mask on a support of 3 L/min O2.
