Effect of gum chewing on reducing postoperative ileus and recovery after colorectal surgery: A randomised controlled trial

AIM

This study aimed to determine the effect of gum chewing on the reduction of postoperative ileus and recovery after surgery.

METHODS

This study was conducted a randomized controlled trial in 60 patients who underwent colorectal surgery between November 2011 and December 2012. Patients in the experimental group chewed gum three times a day. The time of flatus and defecation, the time to start feeding, pain levels and time of discharge were monitored.

RESULTS

Post-surgery results for gum-chewing were first flatus and defecation times and the time to start feeding was shorter; pain levels were lower on the 3rd - 5th days; patients were discharged in a shorter time post-surgery.

CONCLUSIONS

Chewing gum is a simple intervention for reducing postoperative ileus after colorectal surgery. Further studies that examine the effectiveness of gum chewing on other surgical interventions in which the development risk of postoperative ileus should be performed.

Implementing fast-track protocol for colorectal surgery: a prospective randomized clinical trial

BACKGROUND

Fast-track protocols are followed by an enhanced recovery, early return to bowel function and to complete nutrition, and a reduced hospital stay. Our study was designed to implement fast-track protocol in our university hospital.

METHODS

The 96 consecutive patients with colorectal neoplasm included in the study were randomized in two equal groups: group 1 (FT) included patients undergoing colorectal surgery in a fast-track protocol, and group 2 (C) included patients undergoing colorectal surgery with a conventional care protocol. As with other fast-track protocols, our protocol included carbohydrate fluids load before operation, early mobilization and oral feeding, regular prokinetics, and multimodal postoperative analgesia. Time to restoration of bowel function, to complete mobilization and feeding, length of hospital stay, and incidence of complications and readmissions were monitored.

RESULTS

Time to mobilization, restoring of bowel function, and complete oral feeding were significantly shorter with fast-track protocol (p = 0.001, p = 0.042, and p = 0.01, respectively). Hospital stay also was shorter in the fast-track group (p = 0.001). The incidence of complications did not significantly differ with the study groups.

CONCLUSIONS

In our study, fast-track protocol resulted in a shorter time to mobilization, complete feeding, and discharge from hospital. Fast-track protocol did not increase the incidence of complications. However, we consider that our data require further confirmation with powered multicenter national studies.

Low plasma albumin linked to fluid overload in postoperative epidural patients

INTRODUCTION

Hypotension is commonly associated with epidural use in postoperative patients and is usually treated with fluid or vasopressor therapy. The former can result in fluid overload, associated with significant morbidity. This study aimed to identify factors increasing the likelihood of fluid overload in elective patients.

PATIENTS AND METHODS

A prospective audit of fluid therapy in elective, postoperative, epidural patients was carried out over a 6-week period in a teaching hospital in England. Demographic, biochemical, and fluid balance data were collected and analysed to determine which factors had the strongest correlation with fluid overload. Fluid overload was calculated as the percentage of net fluid input relative to pre-operative body weight (%FO).

RESULTS

Thirty-two patients were included in this study. An overload of 10% of the patients' pre-operative body weight was considered significant. The mean fluid overload incurred by patients in this study was 8.17 l (range, 2.89-14.62 l); %FO was 11.32% (range, 3.67-26.10%). The strongest independently correlating factor to fluid overload was initial, postoperative plasma albumin. Patients with a plasma albumin less than 27 g/l developed significant overload: mean overload 9.75 l (range, 2.89-14.62 l), %FO 15.12% (range, 4.81-26.10%), whilst those with an albumin level greater than 27 g/l did not: mean overload 6.77 l (range, 3.34-11.48 l), %FO 7.96% (range, 3.67-13.93%); P = 0.0001.

CONCLUSIONS

Patients receiving epidurals with initial, postoperative, plasma albumin levels below 27 g/l are at increased risk of significant fluid overload. Earlier instigation of vasopressor therapy in this subgroup of patients may help prevent this.
