EXTRADURAL BUPIVACAINE AND METHADONE FOR EXTRACORPOREAL SHOCK-WAVE LITHOTRIPSY †

Pulse oximetry during extradural analgesia for extracorporeal shock wave lithotripsy.

Exracorporeal shock wave lithotripsy (ESWL) may require immersion of the patient in water and extradural blockade for analgesia, which may both affect pulmonary and cardiovascular function and increase the likelihood of hypoxaemia. Twenty-four patients (ASA I-III) with extradural blockade and six healthy subjects were studied by pulse oximetry during immersion. Oxygen saturation (SaO2) tended t...

[Extracorporeal shock-wave lithotripsy].

Concrement lithotripsy in the kidney and ureter using extracorporeal shock waves (ESWL) was performed with the aid of a 2nd-generation lithotriptor--Lithostar Siemens. Over a period of 11 months ESWL was applied in 526 patients aged 7 to 80 years, 10 of these were children. 19 patients had bilateral lithiasis so that the treatment was applied to a total of 545 renoureteral units and 698 concrem...

General anesthesia for extracorporeal shock wave lithotripsy.

Extracorporeal shock wave lithotripsy of pancreatic stones.

Extracorporeal shock wave lithotripsy of pancreatic stones was performed in eight patients with chronic pancreatitis and a dilated duct system harbouring stones 5 to 20 mm (means 10 (SD) 5 mm) in diameter. After endoscopic sphincterotomy of the pancreatic orifice the stones were disintegrated by shock waves under fluoroscopic control using a kidney lithotripter (Dornier HM3). The procedure was ...

[Stone burden on extracorporeal shock wave lithotripsy].

Based on the 89 stones treated by ESWL therapy alone, the factors which influence the number of ESWL shots were analyzed. Stone volume was calculated by summing up the value "length x short axis" for each stone. The value correlated well with the number of shots needed to disintegrate the stone (p less than 0.01). The stones below the pelvis-ureteral junction needed twice shots compared with st...
