Remifentanil compared with sufentanil during extra-corporeal shock wave lithotripsy with spontaneous ventilation: a double-blind, randomized study.

BACKGROUND: The pharmacokinetic properties of remifentanil may allow a rapid analgesic action during painful procedures and short lasting postoperative respiratory depression. METHODS: We carried out a randomized, blind, study in 60 patients to compare remifentanil (continuous i.v. infusion starting at 0.025 micro g kg(-1) min(-1)) and sufentanil (i.v. doses of 0.15 micro g kg(-1)) during extra-corporeal shock wave lithotripsy (ESWL). Pain was assessed using a numerical pain scale (0-100), and pain relief was defined as a score < or =30. Respiratory depression was defined as a ventilatory frequency less than10 breaths min(-1) on two occasions or a peripheral oxygen saturation < or =92%, or administration of naloxone. RESULTS: The quality of analgesia was similar in both groups, during and after ESWL. During ESWL, there was no significant difference in respiratory depression in the remifentanil and sufentanil groups (53 vs 73%, NS). The percentage of satisfied patients (73 vs 83%, NS) and satisfied surgeons (97 vs 100%, NS) did not significantly differ between groups. After the procedure patients given remifentanil had less respiratory depression (20 vs 53%, P<0.05) and less nausea and vomiting (3 vs 20%, P<0.05). CONCLUSION: A continuous i.v. infusion of remifentanil provided comparable analgesia and caused less respiratory depression and nausea and vomiting than i.v. boluses of sufentanil in patients undergoing extra-corporeal shock wave lithotripsy.

[Assessment of hemorrhage risk of transvesical prostatectomy with bladder neck cerclage].

OBJECTIVE: Evaluation of blood loss and predictive factors of haemorrhagic complications of transvesical prostatectomy. MATERIAL AND METHODS: From January 1994 to December 1998, 202 patients with a mean age of 70.5 +/- 7.4 years (range: 46.6-89.3 years) were operated for benign prostatic hyperplasia with a mean prostate weight of 86 +/- 33 g. Transvesical prostatectomy was performed with bladder neck cerclage and suction drainage of the prostatectomy site for 48 hours. 107 patients donated blood preoperatively (mean: 2.8 +/- 0.7 units) to allow possible autotransfusion. Blood losses were evaluated by determining haematocrit during hospitalisation, the quantity of blood collected intraoperatively and the presence of postoperative bleeding possibly requiring surgical revision. RESULTS: The calculated overall blood loss was 435 +/- 306 ml of RBC, i.e. 1783 ml for an haematocrit of 30%. A high ASA score was significantly related with higher blood loss and preoperative anticoagulant treatment. No predictive factor for intraoperative bleeding (mean: 519 +/- 327 ml) was identified. Absence of the median lobe and a high ASA score were also predictive factors of postoperative bleeding. Age, operating time, prostate weight, recent urinary tract infection, preoperative drainage, preoperative haematocrit, and preoperative blood donation (autotransfusion) did not significantly influence the volume of blood loss. CONCLUSION: Apart from the ASA score, no predictive factor for the severity of bleeding associated with transvesical prostatectomy was defined in order to identify a group of patients at higher risk of severe bleeding.

[Empirical treatment of urinary infections in urologic surgery].

Emergency prescription of empirical antibiotic therapy is justified in a context of febrile urinary tract infection, or to shorten the preoperative period in a hospitalised infected patient. The severity of the infection, its origin (community or nosocomial), morphological characteristics of the bacteria on direct examination, and urinary dip-stick data must be taken into account to select the most appropriate antibiotic while waiting for the antibiotic susceptibility test results.

[Propofol or ketamine in anesthesia of the very old patient. Study of the hemodynamic effects during induction].

The haemodynamic changes following anaesthesia for hip surgery in 16 very old ASA II or III patients (mean age 85.8 +/- 5 years) were studied. Patients were randomly assigned to two groups: group I 1 mg X kg-1 propofol, group II 1.5 mg X kg-1 ketamine. After injection, the patients were left spontaneously breathing oxygen, and were assisted when apneic. Haemodynamic measures with a Swan-Ganz catheter and thermodilution cardiac output calculator were made before and 1, 3, 5, 10 and 15 min after anaesthetic induction. The two groups were similar in age, weight and mean arterial pressure, but statistically different for some haemodynamic parameters (Ppa, Ppw, CI). In group I, arterial pressure fell significantly (-17%) in the first minute and continued to fall (-15%) until the 15th min. Heart rate remained unchanged: right atrial and pulmonary pressures were not changed; cardiac index fell slightly and MVO2 estimated by the triple product fell (-27%) as soon as propofol was infused. There was no clinical sign of cardiac failure. In group II, arterial pressure increased significantly, and heart rate decreased; pulmonary capillary wedge pressure increased (+93% after the 3rd min) and cardiac index was unchanged. The ventricular function curve was shifted to the right, suggesting a decrease in inotropism. Systemic vascular resistances were steady. MVO2 increased twofold, mainly due to the rise in pulmonary capillary wedge pressure.(ABSTRACT TRUNCATED AT 250 WORDS)
