title: Spinal Anesthesia Facilitates the Early Recognition of TUR Syndrome.
abstract: OBJECTIVE
  To investigate what clinical features typically present in transurethral resection (TUR) syndrome and to see which classically present first. The purpose of the study was to establish whether or not a particular method of anesthesia is preferred in detecting this syndrome in its early stages.
  
  
  METHODS
  A total of 1,502 transurethral resection of the prostate (TURP) over a 15 year period were reviewed to see which, if any, went on to experience this complication. Of these cases, 48 developed TUR syndrome. The case records were reviewed retrospectively and the presenting clinical features were analysed. All TURPs were routinely performed under spinal anesthesia and followed a standardised set up. The irrigation fluid used in all operations was Glycine 1.5%.
  
  
  RESULTS
  Forty eight patients displayed clinical features of TUR syndrome giving an incidence of 3.2%. Trainees of varying experience caused all but one case. Median resection time, resection weight and volume of intraoperative glycine irrigation fluid were 55 minutes (range 40-75 minutes), 44 grams (range 24-65 g), and 28 l (24-48 l) respectively. Only 16/48 TURPs had a recorded capsular perforation. Pre- vs. post-operative median hematocrit, hemoglobin and serum sodium were 0.42 vs. 0.33, 14.2 g/dl vs. 10.1 g/dl and 142 mmol/l vs. 121 mmol/l respectively. Patients presented with nausea 44/48, vomiting 28/48, visual disturbance 29/48, apprehension 37/48, disorientation 17/48, breathing difficulties 17/48, and bradycardia 19/21. The earliest observed sign was nausea 21/48, then bradycardia 11/48, apprehension 11/48, and visual disturbance 10/48; after which the procedure was abandoned. None of the patients developed stupor, coma or seizures. Out of the 48 patients, 9 were admitted to high dependency units and all of these were treated with IV furosemide. One patient required a blood transfusion. All patients recovered within 48 hours (range 18-48 hours) and none had any long term complications on follow up.
  
  
  CONCLUSIONS
  The features most associated with the early presentation of TUR syndrome require the patient to be conscious for detection. The use of spinal anaesthesia is therefore desirable to facilitate its early recognition.
