Letter to the Editor: In Response
Our study indicated that alleviating dehydration with adequate fluid therapy reduces the incidence of postoperative adverse outcomes such as thirst, nausea, dizziness, and drowsiness. This was studied in dilatation and curettage procedure, orthopedic surgery, laparoscopy, and general surgery. The majority of the patients studied underwent the dilatation and curettage procedure. We agree that dilatation and curettage are short surgical procedures. Different anesthetic techniques can be used. However, the difference in adverse outcomes was significant between those who received 20 mL/kg of isotonic electrolyte solution and those who did not. Therefore, the results can be applicable to the longer and more complex ambulatory surgical procedures.
In this study, the speed of recovery was assessed by the postanesthesia discharge scoring system (PADSS). In the results section, we indicated that the time taken to achieve PADSS >or=to 9 was not significantly different between the two groups (1.3 +/- 0.8 vs 1.5 +/- 0.4 h). One important finding is that these adverse outcomes persisted at 24 h. We stress that perioperative fluid hydration is a simple procedure and ambulatory patients will benefit from it.
