Should Adult Patients Drink Fluids Before Discharge From Ambulatory Surgery?

Postoperative fasting after general anaesthesia: A survey of French anaesthesiology practices

BACKGROUND

Preoperative fasting is well codified worldwide. In contrast, the literature on the postoperative fasting (POF) is scarce, leading to potentially wide discrepancies among anaesthesiology practices. This survey assessed French POF practices.

METHODS

From March 2013 to January 2014, a survey was conducted among anaesthesiologists, members of the French Society of Anaesthesiology and Intensive Care Medicine (SFAR). The POF durations of either fluid or solid food intake was assessed according to airway management procedures (endotracheal intubation [EI] or laryngeal mask [LMA]) and age of the patients (adult or paediatric).

RESULTS

Seven hundred and fifty-four surveys were returned (67% from public hospital practitioners and 33% from private hospital and clinic practitioners). The majority of anaesthesiologists allowed fluid intake 2h after EI and immediately after discharge from PACU following LMA. For solid food resumption, it was 2h for children and 4h for adults after EI and 2h for both children and adults after LMA. Regardless of the airway management procedures, fasting was permitted immediately after PACU discharge more frequently in public than in private hospitals (36% vs. 33%, P<0.05). Four hours after the end of surgery, the rate was significantly higher in private than in public hospitals (93% vs. 89 %, P<0.001).

CONCLUSIONS

All in all, POF lasted less than 4hours after surgery regardless of airway management. They were shorter with regard to fluid intake, paediatric patients and LMA in comparison with solid food, adult patients and EI respectively.

Factors affecting recovery and discharge following ambulatory surgery

PURPOSE

Recovery and discharge following ambulatory surgery are important components of the ambulatory surgery experience. This review provides contemporary perspectives on the issues of discharge criteria, fast-tracking, patient escort requirements, and driving after ambulatory anesthesia.

SOURCE

A search was performed in the Cochrane Central Register for Controlled Trials, MEDLINE(R), EMBASE(R), CINAHL, and PsycINFO, to review factors delaying discharge following ambulatory surgery. The following subject headings were used: "ambulatory surgery, discharge, recovery, car driving, escort, transport, fast tracking, patient discharge, recovery, transportation of patients, hospital discharge, recovery room, patient transport, hospital discharge, recovery room, anesthetic recovery, patient transport, ambulatory surgical procedures, patient discharge, recovery of function, automobile driving, patient escort service, recovery room". Using the same search engines, the following keywords were used: "fast tracking, recovery, and discharge".

PRINCIPAL FINDINGS

The current literature supports that discharge scoring systems may be useful to guide discharge following ambulatory surgery. While fast-tracking has become common in some centres, further studies are required to justify more routine implementation of this practice in the management of patients undergoing ambulatory surgery. Patients at low risk for urinary retention can be discharged home without voiding. Patients should not drive until at least 24 hr postoperatively.

CONCLUSIONS

Ensuring rapid postoperative recovery and safe discharge following ambulatory surgery are important components of the ambulatory surgical program. A clearly defined process should be established for each ambulatory surgical unit to ensure the safe and timely discharge of patients after anesthesia, in accordance with current best evidence.
