Sixteen otherwise healthy women undergoing cholecystectomy were randomized to receive postoperative analgesia either by continuous infusion of papaveretum (n = 8), or by continuous interpleural infusion of bupivacaine (n = 8). Postoperative pain was assessed by linear analogue and ventilatory capacity. Changes in body protein were measured by in vivo neutron activation analysis. Clinical course was also noted. Pain scores were significantly lower in the interpleural group over the first 48 h (P less than 0.02). Ventilatory capacity was also significantly better for the first 24 h (P less than 0.025). There was no evidence of shortened postoperative ileus; hospital stay and postoperative fatigue were similar for the two groups. Weight and protein losses over a 2 week period were similar in the two groups. It is concluded that the apparent advantages in patient comfort and mobility offered by interpleural infusion are most marked in the first 48 h postoperatively, with an advantage in ventilatory capacity over the first 24 h.

Few advancements in postoperative pain control in children have been made despite longstanding inadequacies in conventional intramuscular analgesic regimens. While overestimating narcotic complication rates, physicians often underestimate efficacious doses, nurses are reluctant to give injections, and many children in pain shy away from shots. This study prospectively focuses on the safety, efficacy, and complication rate of intermittent intramuscular (IM) versus continuous intravenous infusion (IV) of morphine sulfate (MS) in 46 nonventilated children following major chest, abdominal, or orthopedic surgical procedures. Twenty patients assigned to the IM group had a mean age of 6.17 years and a mean weight of 23.0 kg. Twenty-six patients assigned to the IV group had a mean age of 8.74 years and a mean weight of 27.4 kg. The mean IM MS dose was 12.3 micrograms/kg/h while the mean IV dose was 19.8 micrograms/kg/h (P less than .001). Postoperative pain was assessed with a linear analogue scale from 1 to 10 (1, "doesn't hurt"; 10, "worst hurt possible") for 3 days following operation. Using the analysis of covariance (ANACOVA), nurse, parent, and patient mean pain scores in the IV group were significantly lower than those of the IM group when controlled for age, MS dose, and complications (P less than .007). Nurse assessment of pain correlated well with the patient and parent assessments (Pearson correlation coefficients greater than 0.6). Not only did IV infusion give better pain relief than IM injections, but there were no major complications such as respiratory depression. Minor complications in this study (nausea, urinary retention, drowsiness, vomiting, hallucinations, lightheadedness, and prolonged ileus) were not significantly different between IM and IV groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Our objective was to determine the least invasive surgical procedure; to do this we compared postoperative pain, duration of ileus, and level of neurohormonal stress response after laparoscopic cholecystectomy (LC) and open cholecystectomy (OC). Postoperative recovery of patients was faster after LC than OC but comparison of the neurohormonal stress response after laparoscopic and open surgical procedures revealed conflicting results. Forty-one consecutive patients with noncomplicated gallstones were randomized for LC (N = 25) and OC (N = 16). The stress level was evaluated in patients before surgery by the Hamilton anxiety scale. Postoperative pain was assessed by a visual analogic scale (VAS) pain score and by the amount of analgesic drugs (propacetamol) administered, while the duration of ileus was determined by the delay between surgery and the time to first passage of flatus as well by the colonic transit time (CTT) measured by radiopaque markers. Plasma concentrations of anti-diuretic hormone (ADH), adrenocorticotropic hormone (ACTH), beta-endorphin (BE), neurotensin (NT), and aldosterone (Ald) were measured before and during surgery as well as 2 and 5 hr after the surgery (D0) and on the day following surgery (D1). Urinary cortisol (uCOR) and urinary catecholamine metabolites were assessed before surgery, during D0, and on D1. Patient characteristics, the duration of surgery, and the doses of anesthetic drugs were not different in LC and OC. In LC patients the VAS pain score and the doses of postoperative antalgics were lower (P < 0.05), the time to first passage of flatus was shorter (P < 0.001), and the CTT tended to be shorter (54 +/- 12 hr vs 81 +/- 17) compared to OC patients. Patients who required the highest doses of postoperative antalgics had the longest delay to first passage of flatus (P < 0.01). During surgery, all neurohormonal parameters increased compared to the preoperative period (P < 0.05), and only plasma NT concentrations were lower during LC than OC (P < 0.05). During the postoperative period, ACTH, BE, Aid, catecholamines, and uCOR concentrations were lower in LC than in OC (P < 0.05). Concentrations of hormonal parameters were higher when the duration of surgery increased (P < 0.05). A greater need for propacetamol to relieve pain was associated with a greater increase in BE, ACTH, and urinary catecholamine levels (P < 0.05-P < 0.005). When the time to first passage of flatus was delayed, levels of BE, ACTH, and catecholamines and NT concentrations were increased (P < 0.05-P < 0.005). In conclusion, LC is less invasive because this surgical procedure induces a shorter neurohormonal stress response than OC, even if the peroperative response is not different. Postoperative pain levels and the duration of ileus are associated with BE, ACTH, and catecholamine levels and NT concentrations, suggesting the importance of hormones in postoperative functional recovery.

We describe 50 patients who recently underwent laparoscopic surgery. Early results, complications, and follow-up data were collected prospectively. Of 50 patients, 34 had an incisional hernia, whereas 16 had a primary defect. Three trocars were inserted. EndoShears or Ultracision was used for tissue manipulation. The prosthetic mesh used was an expanded polytetrafluoroethylene (ePTFE) mesh, inserted through the first trocar and fixed with a helicoidal stapler. Patients were followed-up in the outpatient clinic (mean, 14 months). Every operation was successfully completed, and mean operative time was 103 minutes. There were two small bowel injuries (4%) repaired by minilaparotomy. Postoperative pain was limited. Bowel movements, ambulation, and discharge were prompt. We noted 4 cases of urinary retention (8%), 8 seromas (16%), and 1 prolonged ileus, which resolved on day 5 spontaneously. Mean postoperative stay was 4 days. One patient was readmitted after 4 weeks because of incomplete obstruction, resolved conservatively. There has been only 1 recurrence (2%), 8 months after the operation. The technique appears safe and efficacious.

Laparoscopic surgery has been increasingly used in different fields of surgery. This report concerns the authors' experience with combined laparoscopic cholecystectomy and symptomatic renal cyst decortication. The mean diameter of the cysts was 11.2 cm. and involved the left and right kidney in 3 and 1 patient, respectively. All cysts were peripheral. Surgery was performed using 4 trocars in 3 cases and 5 trocars in the other. The mean operative time was 110 minutes and mean blood loss 40 cc. Postoperative pain was minimal. The mean duration of postoperative ileus was 2.2 days. No significant complications were observed. The mean postoperative hospital stay was 3.5 days. At follow-up examinations all patients were pain-free. Recurrence of the cyst was observed in only one case. Combined laparoscopic cholecystectomy and renal cyst decortication is technically feasible in selected cases and does not seem to significantly affect the perioperative course of cholecystectomy.

We describe the whole cohort of patients operated on laparoscopically for ventral hernias at our institution. Information on early results, complications, and long-term follow-up was collected prospectively. Of 90 operations attempted, five (5.8%) required conversion. Of the remaining 85 patients, 65 (76%) had an incisional hernia, while 20 (24%) had primary defects. Three trocars were routinely employed (Hasson and two 5-mm). The prosthetic mesh used was ePTFE inserted through the first trocar and fixed using helicoidal staplers. Patients were periodically followed in the outpatient clinic for at least 12 months postoperatively and contacted at the time of this review. Mean operative time was 101 min. We had three small bowel injuries repaired laparoscopically. Postoperative pain was limited. Bowel movements, deambulation, and discharge were prompt. We had six (7%) urinary retentions, eight (9%) seromas, three (3.5%) cases of pneumonia, two (2%) cases of postoperative vomiting, and one (1%) prolonged ileus, which resolved spontaneously on postoperative day 2. Mean postoperative stay was 4 days. One patient was readmitted after 4 weeks with incomplete obstruction, resolved conservatively. There were three recurrences (3.5%), which developed within 1 year of the operation, and a trocar-site herniation (1%). The technique appears safe and efficacious.

A combined strategy of anesthetic and surgical care defines postoperative rehabilitation, which aims to accelerate recovery from surgery, shorten convalescence, and reduce postoperative morbidity. Preoperative and early postoperative oral feeding, a relatively "dry" fluid regimen, and the avoidance of or early removal of drains, gastric tubes and bladder catheters all contribute to decreasing postoperative morbidity after abdominal surgery. Postoperative pain control, prevention of nausea and vomiting, shortening the duration of postoperative ileus, and early ambulation can also help to decrease postoperative morbidity. The use of multimodal fast-track clinical rehabilitation programs should improve outcomes and quality of life, reduce hospital stays, and save money.

Postoperative pain continues to be inadequately managed. While opioids remain the mainstay for postoperative analgesia, their use can be associated with adverse effects, including ileus, which can prolong hospital stay. A number of studies have investigated the use of perioperative intravenous lidocaine infusion for improving postoperative analgesia and enhancing recovery of bowel function. This systematic review was performed to determine the overall efficacy of intravenous lidocaine infusion on postoperative analgesia and recovery from surgery in patients undergoing various surgical procedures. We searched the databases of MEDLINE, CINAHL and the Cochrane Library from 1966 to December 2009. We searched for randomized controlled comparisons of lidocaine infusion with placebo in the surgical setting and reporting on postoperative analgesia and other aspects of patient recovery from surgery. The quality of all included studies was assessed using the Modified Oxford Scale. Information on postoperative pain intensity and analgesic requirements was extracted from the trials and compared qualitatively. Other relevant data such as return of bowel function, length of hospital stay, intraoperative anaesthetic requirement and adverse effects were also compared. Sixteen trials were included. A total of 395 patients received intravenous lidocaine with 369 controls. In open and laparoscopic abdominal surgery, as well as in ambulatory surgery patients, intravenous perioperative infusion of lidocaine resulted in significant reductions in postoperative pain intensity and opioid consumption. Pain scores were reduced at rest and with cough or movement for up to 48 hours postoperatively. Opioid consumption was reduced by up to 85% in lidocaine-treated patients when compared with controls. Infusion of lidocaine also resulted in earlier return of bowel function, allowing for earlier rehabilitation and shorter duration of hospital stay. First flatus occurred up to 23 hours earlier, while first bowel movement occurred up to 28 hours earlier in the lidocaine-treated patients. Duration of hospital stay was reduced by an average of 1.1 days in the lidocaine-treated patients. Administration of intravenous lidocaine infusion did not result in toxicity or clinically significant adverse events. Lidocaine had no impact on postoperative analgesia in patients undergoing tonsillectomy, total hip arthroplasty or coronary artery bypass surgery. In conclusion, intravenous lidocaine infusion in the perioperative period is safe and has clear advantages in patients undergoing abdominal surgery. Patients receiving lidocaine infusion had lower pain scores, reduced postoperative analgesic requirements and decreased intraoperative anaesthetic requirements, as well as faster return of bowel function and decreased length of hospital stay. Further studies are needed to assess whether lidocaine has a beneficial effect in patients undergoing other types of surgery and to determine the optimum dose, timing and duration of infusion of lidocaine in this setting.

Postoperative pain is one of the major complications in general and bariatric surgery, associated with ongoing problems such as ileus, pneumonia and prolonged mobilization. In this study, patients undergoing bariatric surgery were analyzed according to their postoperative pain relief regime. In one group patients were treated with a patient-controlled analgesia (PCA) device, while the other group was treated with oral and intravenous analgesic medication. The aim of this study was to analyze which postoperative pain relief therapy would be more appropriate. We chose the Cumulative Analgesic Consumption Score (CACS) and Numeric Rating Scale (NRS) for pain measurement. For better comparison, we performed a modification of CACS according to PCA treatment. We observed better pain relief in the PCA group. Furthermore, we observed an advantage of treatment with laxatives in patients treated with PCA. In conclusion, PCA devices are appropriate instruments for postoperative pain relief in bariatric patients. CACS is a practical tool for postoperative pain measurement, describing individual pain sensation more objectively, although holding further potential in modification.
