Objectives:To compare sedoanalgesia achieved using propofol-fentanyl-ketamine (PFK) combination with general anesthesia (GA) in terms of safety, hemodynamic stability, and perioperative complications.Methods:Patients in the GA group were anesthetized using fentanyl (2 μg kg-1) and propofol (2 mg kg-1). The PFK group was anesthetized using a mixture of which each one ml contains 0.005 mg of fentanyl, 5 mg of propofol, 5 mg of ketamine, and 2 mg of lidocaine. Patients received an initial dose of 0.05 ml kg-1, followed by 0.05 mg kg-1 60 seconds later. Maintenance boluses of 0.025 ml kg-1 were administered every 3-5 minutes. Respiration occurred spontaneously through a simple face mask with 3 L min-1 O2.Results:The GA group had 37 (37%) patients develop hypotensive episodes, compared to one (1%) episode in the PFK group (p<0.001). Five (5%) patients in the PFK group had an episode of transient O2 desaturation, compared to one (1%) patient in the GA group (p=0.212). The duration of induction and termination of anesthesia were significantly shorter in the PFK group (p<0.001).Conclusion:The PFK combination herein described is safe, effective, and provides intraoperative hemodynamic stability in patients with multiple comorbidities undergoing urological procedures.  相似文献

Tremor is the most common and frequently reported movement disorder in multiple sclerosis (MS). Paroxysmal dystonia (PD), also known as painful tonic spasm (PTS), is a relatively less common but well-recognized movement disorder in multiple sclerosis (MS). These are characterized by episodic attacks of involuntary flexion, extension movements of body. Such paroxysmal symptoms as an initial presenting feature raise many differential diagnoses and can often be mistaken as epileptic seizures as well as psychogenic events and may sometimes lead to delay in diagnosis as well. Diagnosis is clinical with the help of supportive investigations to rule out other paroxysmal disorders, especially epileptic seizures. We describe a case of a young lady, who was referred to us as a case of refractory seizure and diagnosed as having paroxysmal dystonia as a first manifestation of MS, with complete resolution of her symptoms after successful treatment with anti-epileptic drugs.

Paroxysmal dystonia (PD), also called Painful tonic spasm (PTS), is a well-recognized and the most frequently observed movement disorder in multiple sclerosis.1 The PD is classified as 4 types according to the precipitating factors, phenomenology, duration of attacks, and etiology. Paroxysmal kinesigenic dyskinesia (PKD) is induced by sudden movement, paroxys¬mal non-kinesigenic dyskinesia occurs spontaneously, paroxysmal exertion-induced dyskinesia appears after prolonged exercise, and paroxysmal hypnogenic dyskinesia occurs during sleep.2 These disorders have often been misdiagnosed as partial onset epilepsy initially and later identified as movement disorder secondary to MS. Treatment of underlying disease along with symptomatic treatment may alleviate the symptoms significantly. We described a case of a young lady who was referred to us as a case of psychogenic non-epileptic events. Diagnosis of MS manifesting with PD was established. She was started on disease modifying therapy for MS as well as Carbamazepine for her PD. She showed a remarkable improvement on these treatments and was followed up in MS clinic with no new MS relapse or recurrence of PD for 18 months after the initial presentation.  相似文献
