Is patient outcome affected by the administration of intravenous fluid during bowel preparation for colonic surgery?

Abstract：

INTRODUCTION:We have previously shown that Picolax bowel preparation causes a significant dehydrating effect, which can be minimised by administering a calculated volume of intravenous fluid. The aim of this prospective study was to assess whether peri-operative outcome is affected by administering a calculated volume of intravenous fluid during bowel preparation. PATIENTS AND METHODS:Patients having bowel preparation (Picolax: Ferring Pharmaceuticals Ltd, Middlesex, UK) prior to colonic surgery were prospectively randomised to receive no intravenous fluid (group 1) or calculated intravenous crystalloid based on their body weight (group 2), during preparation. In both groups, transfusion was protocol-driven. Outcome variables measured included intra-operative and postoperative intravenous fluid requirement, hourly recorded urine output for 24 h, number of patients transfused, number of units of blood transfused, time to the passage of flatus, time to having their bowels open, time until tolerating a full diet, complications and length of stay in hospital. RESULTS:Thirty-three patients were recruited - group 1 (n = 18) and group 2 (n = 15). There were 24 men and 9 women, median age 69 years (range, 29-86 years). There was no significant difference between the groups with respect to age, sex, weight, ASA grade, pre-operative haemoglobin concentration, duration or type of operation. The total number of patients receiving a transfusion (P = 0.026) and the number of units of blood transfused (P = 0.017) was significantly greater in group 1. The number of units of blood transfused intra-operatively was significantly greater in group 1 (P = 0.029). Significantly fewer patients had a urine output < 30 ml/h in the first 24-h after operation (P = 0.046) in group 2. There was no difference between groups in other outcomes measures. CONCLUSIONS:This study indicates that a calculated volume of intravenous fluid administered during bowel preparation improves patient outcomes with respect to blood transfusion and postoperative oliguria. We advocate calculated intravenous fluid administration in all patients undergoing bowel preparation prior to colonic surgery.
