To investigate the effect of a restricted intravenous fluid regimen versus a standard regimen on complications after colorectal resection. Current fluid administration in major surgery causes a weight increase of 3-6 kg. Complications after colorectal surgery are reported in up to 68% of patients. Associations between postoperative weight gain and poor survival as well as fluid overload and complications have been shown. We did a randomized observer-blinded multicenter trial. After informed consent was obtained, 172 patients were allocated to either a restricted or a standard intraoperative and postoperative intravenous fluid regimen. The restricted regimen aimed at maintaining preoperative body weight; the standard regimen resembled everyday practice. The primary outcome measures were complications; the secondary measures were death and adverse effects. The restricted intravenous fluid regimen significantly reduced postoperative complications both by intention-to-treat (33% versus 51%, P = 0.013) and per-protocol (30% versus 56%, P = 0.003) analyses. The numbers of both cardiopulmonary (7% versus 24%, P = 0.007) and tissue-healing complications (16% versus 31%, P = 0.04) were significantly reduced. No patients died in the restricted group compared with 4 deaths in the standard group (0% versus 4.7%, P = 0.12). No harmful adverse effects were observed. The restricted perioperative intravenous fluid regimen aiming at unchanged body weight reduces complications after elective colorectal resection.

To determine whether an intervention with smoking cessation starting 4 weeks before general and orthopedic surgery would reduce the frequency of postoperative complications. Complications are a major concern after elective surgery and smokers have an increased risk. There is insufficient evidence concerning how the duration of preoperative smoking intervention affects postoperative complications. A randomized controlled trial, conducted between February 2004 and December 2006 at 4 university-affiliated hospitals in the Stockholm region, Sweden. The outcome assessment was blinded. The follow-up period for the primary outcome was 30 days. Eligibility criteria were active daily smokers, aged 18 to 79 years. Of the 238 patients assessed, 76 refused participating, and 117 men and women undergoing surgery for primary hernia repair, laparoscopic cholecystectomy, or a hip or knee prosthesis were enrolled. Smoking cessation therapy with individual counseling and nicotine substitution started 4 weeks before surgery and continued 4 weeks postoperatively. The control group received standard care. The main outcome measure was frequency of any postoperative complication. An intention-to-treat analysis showed that the overall complication rate in the control group was 41%, and in the intervention group, it was 21% (P = 0.03). Relative risk reduction for the primary outcome of any postoperative complication was 49% and number needed to treat was 5 (95% CI, 3-40). An analysis per protocol showed that abstainers had fewer complications (15%) than those who continued to smoke or only reduced smoking (35%), although this difference was not statistically significant. Perioperative smoking cessation seems to be an effective tool to reduce postoperative complications even if it is introduced as late as 4 weeks before surgery.

Smoking and hazardous drinking are common and important risk factors for an increased rate of complications after surgery. The underlying pathophysiological mechanisms include organic dysfunctions that can recover with abstinence. Abstinence starting 3–8 weeks before surgery will significantly reduce the incidence of several serious postoperative complications, such as wound and cardiopulmonary complications and infections. However, this intervention must be intensive to obtain sufficient effect on surgical complications. All patients presenting for surgery should be questioned regarding smoking and hazardous drinking, and interventions appropriate for the surgical setting applied.

Objective: To evaluate the outcome after spinal surgery when adding prehabilitation to the early rehabilitation. Design: A randomized clinical study. Setting: Orthopaedic surgery department. Subject: Sixty patients scheduled for surgery followed by inpatient rehabilitation for degenerative lumbar disease. Interventions: The patients were computer randomized to prehabilitation and early rehabilitation (28 patients) or to standard care exclusively (32 patients). The intervention began two months prior to the operation. The prehabilitation included an intensive exercise programme and optimization of the analgesic treatment. Protein drinks were given the day before surgery. The early postoperative rehabilitation included balanced pain therapy with self-administered epidural analgesia, doubled intensified mobilization and protein supplements. Main measures: The outcome measurements were postoperative stay, complications, functionality, pain and satisfaction. Results: At operation the intervention group had improved function, assessed by Roland Morris Questionnaire (P = 0.001). After surgery the intervention group reached the recovery milestones faster than the control group (1—6 days versus 3—13, P =0.001), and left hospital earlier (5 (3—9) versus 7 (5—15) days, P =0.007). There was no difference in postoperative complications, adverse events, low back pain and radiating pain, timed up and go, sit-to-stand or in life quality. Patient satisfaction was significantly higher in the intervention group compared with the control group. Conclusion: The integrated programme of prehabilitation and early rehabilitation improved the outcome and shortened the hospital stay — without more complications, pain or dissatisfaction.
