Postthoracotomy pain management

Continuous erector spinae plane block versus thoracic epidural analgesia in video-assisted thoracoscopic surgery: a prospective randomized open-label non-inferiority trial

BACKGROUND AND OBJECTIVES

The evolving surgical techniques in thoracoscopic surgery necessitate the exploration of anesthesiological techniques. This study aimed to investigate whether incorporating a continuous erector spinae plane (ESP) block into a multimodal analgesia regimen is non-inferior to continuous thoracic epidural analgesia (TEA) in terms of quality of postoperative recovery for patients undergoing elective unilateral video-assisted thoracoscopic surgery.

METHODS

We conducted a multicenter, prospective, randomized, open-label non-inferiority trial between July 2020 and December 2022. Ninety patients were randomly assigned to receive either continuous ESP block or TEA. The primary outcome parameter was the Quality of Recovery-15 (QoR-15) score, measured before surgery as a baseline and on postoperative days 0, 1, and 2. Secondary outcome parameters included pain scores, length of hospital stay, morphine consumption, nausea and vomiting, itching, speed of mobilization, and urinary catheterization.

RESULTS

Analysis of the primary outcome showed a mean QoR-15 difference between the groups ESP block versus TEA of 1 (95% CI -9 to -12, p=0.79) on day 0, -1 (95% CI -11 to -8, p=0.81) on day 1 and -2 (95% CI -14 to -11, p=0.79) on day 2.

CONCLUSIONS

The continuous ESP block is non-inferior to TEA in video-assisted thoracoscopic surgery.

Surgical Approach and Persistent Opioid Use in Medicare Patients Undergoing Lung Cancer Resection

BACKGROUND

Robotic and video-assisted thoracoscopic surgery (VATS) approaches for lung resection are associated with decreased inpatient opioid use compared with open surgery. Whether these approaches affect outpatient persistent opioid use remains unknown.

METHODS

Non-small cell lung cancer patients aged 66 years or more who underwent lung resection between 2008 and 2017 were identified from the Surveillance, Epidemiology, and End Results-Medicare database. Persistent opioid use was defined as filling an opioid prescription 3 to 6 months after lung resection. Adjusted analyses were performed to evaluate surgical approach and persistent opioid use.

RESULTS

We identified 19,673 patients: 7479 (38%) underwent open surgery, 10,388 (52.8%) VATS, and 1806 (9.2%) robotic surgery. Persistent opioid use was 38% in the entire cohort, including 27% of opioid naïve patients, and highest after open surgery (42.5%), followed by VATS (35.3%) and robotic (33.1%, P < .001). In multivariable analyses, robotic (odds ratio 0.84; 95% CI, 0.72-0.98; P = .028) and VATS (odds ratio 0.87; 95% CI, 0.79-0.95; P = .003) approaches were both associated with decreased persistent opioid use compared with open surgery in opioid naïve patients. At 12 months, patients resected using a robotic approach had the lowest oral morphine equivalent per month compared with VATS (133 vs 160, P < .001) and open surgery (133 vs 200, P < .001). Among chronic opioid patients, surgical approach was not associated with postoperative opioid use.

CONCLUSIONS

Persistent opioid use after lung resection is common. Both robotic and VATS approaches were associated with decreased persistent opioid use compared with open surgery among opioid naïve patients. Whether a robotic approach yields additional long-term advantages over VATS warrants further investigation.

The efficacy and safety of acupuncture assisted anesthesia (AAA) for postoperative pain of thoracoscopy: A protocol for systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Enhanced recovery after surgery suggests the use of multimodal analgesia to optimize the perioperative pain management scheme. At present, studies have shown that the application of acupuncture combined anesthesia in thoracoscopy has achieved good curative effect. However, there is no relevant systematic evaluation. Our study is the first meta-analysis of the effectiveness and safety of acupuncture combined anesthesia in pain management after thoracoscopy, in order to provide strong evidence for clinical support.

METHODS

A comprehensive and systematic literature searching will mainly perform on 7 electronic databases (PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure, Chongqing VIP Information, and WanFang Data, Chinese Biomedical Database) from their inception up to November 30, 2021. We will also search for ongoing or unpublished studies from other websites (eg, PROSPERO, ClinicalTrials.gov, Chinese Clinical Trial Registry) and do manual retrieval for potential gray literature. Only the relevant randomized controlled trials published in English or Chinese were included. Two independent investigators will independently complete literature selection, assessment of risk bias, and data extraction, the disagreements will be discussed with the third party for final decisions. The primary outcome measures: visual analog scale, intraoperative anesthetic dosage, and the consumption of postoperative analgesics. The secondary outcome measures: Pittsburgh Sleep Quality Index, the total sleep time after operation, residence time in the anesthesia recovery room, the duration of hospitalization, and the incidence of adverse reactions and serious events. Assessment of bias risk will follow the Cochrane risk of bias tool. Data processing will be conducted by Stata 15.0 software.

RESULTS

We will evaluate the efficacy and safety of acupuncture assisted anesthesia for postoperative pain after thoracoscopy based on randomized controlled trials.

CONCLUSION

This study can provide more comprehensive and strong evidence whether acupuncture assisted anesthesia is efficacy and safe for postoperative pain in thoracoscopy.

Effects of Transcutaneous Electrical Nerve Stimulation on Pain, Pulmonary Function, and Respiratory Muscle Strength After Posterolateral Thoracotomy: A Randomized Controlled Trial

PURPOSE

To evaluate the effects of transcutaneous electrical nerve stimulation (TENS) compared to placebo TENS and a control group on pain, pulmonary function, respiratory muscle strength, and analgesic medications in the postoperative period of thoracotomy in an Intensive care unit (ICU).

METHODS

Patients who had undergone posterolateral thoracotomy were randomly allocated to receive TENS during ICU stay, or placebo TENS, or into the control group. All groups received conventional physiotherapy. We analysed the intensity of pain, pulmonary function, respiratory muscle strength, and use of analgesia medications. Outcomes were evaluated before surgery, immediately after, 24 and 48 h after ICU admission.

RESULTS

Forty-five patients were included. Regarding pain perception, there was no difference between groups (p = 0.172), but there was a significant reduction in pain intensity for patients receiving TENS after first physiotherapy session compared to baseline (4.7 ± 3.2 vs 3.3 ± 2.6; p < 0.05). All groups had a decrease in forced vital capacity (FVC) after surgery (p < 0.001). There was no difference between the groups regarding the use of analgesic medications, but a higher intake of morphine and acetaminophen were observed for the control (p = 0.037) and placebo group (p = 0.035), respectively.

CONCLUSION

The use of TENS provides a little benefit of pain (in the first 12 h) but failed to demonstrate any improvement in the recovery of ICU patients after 48 h of posterolateral thoracotomy.

Ultrasound-guided continuous femoral nerve block vs continuous fascia iliaca compartment block for hip replacement in the elderly: A randomized controlled clinical trial (CONSORT)

BACKGROUND

Continuous femoral nerve block and fascia iliaca compartment block are 2 traditional anesthesia methods in orthopedic surgeries, but it is controversial which method is better. The objective of this study was to compare the practicality, efficacy, and complications of the 2 modalities in hip replacement surgery in the elderly and to assess the utility of a novel cannula-over-needle set.

METHODS

In this prospective, randomized controlled clinical investigation, 60 elderly patients undergoing hip replacement were randomly assigned to receive either continuous femoral nerve block or continuous fascia iliaca compartment block. After ultrasound-guided nerve block, all patients received general anesthesia for surgery and postoperative analgesia through an indwelling cannula. Single-factor analysis of variance was used to compare the outcome variables between the 2 groups.

RESULTS

There was a significant difference between the 2 groups in the mean visual analog scale scores (at rest) at 6 hours after surgery: 1.0 ± 1.3 in the femoral nerve block group vs 0.5 ± 0.8 in the fascia iliaca compartment block group (P < 0.05). The femoral nerve block group had better postoperative analgesia on the medial aspect of the thigh, whereas the fascia iliaca compartment block group had better analgesia on the lateral aspect of the thigh. There were no other significant differences between the groups.

CONCLUSIONS

Both ultrasound-guided continuous femoral nerve block and fascia iliaca compartment block with the novel cannula-over-needle provide effective anesthesia and postoperative analgesia for elderly hip replacement patients.

Comparison of intravenous morphine, epidural morphine with/without bupivacaine or ropivacaine in postthoracotomy pain management with patient controlled analgesia technique

BACKGROUND AND OBJECTIVES

The aim of this randomized, double-blinded, prospective study was to determine the effectiveness and side effects of intravenous or epidural use of morphine, bupivacaine or ropivacaine on post-thoracotomy pain management.

METHODS

Sixty patients undergoing elective thoracotomy procedure were randomly allocated into 4 groups by the sealed envelope technique. Group IVM, EM, EMB and EMR received patient controlled intravenous morphine, and epidural morphine, morphine-bupivacaine and morphine-ropivacaine, respectively. Perioperative heart rate, blood pressure and oxygen saturation and postoperative pain at rest and during cough, side effects and rescue analgesic requirements were recorded at the 30(th) and 60(th) minutes and the 2(nd), 4(th), 6(th), 12(th), 24(th), 36(th), 48(th), and 72(nd) hour.

RESULTS

Diclofenac sodium requirement during the study was lower in Group EM. Area under VAS-time curve was lower in Group EM compared to Group IVM, but similar to Group EMB and EMR. Pain scores at rest were higher at the 12, 24, 36, and 48(th) hour in Group IVM compared to Group EM. Pain scores at rest were higher at the 30(th) and 60(th) minutes in Group EM and Group IVM compared to Group EMB. Pain scores during cough at the 30(th) minute were higher in Group EM compared to Group EMB. There was no difference between Group IVM and Group EMR.

CONCLUSIONS

Morphine used at the epidural route was found more effective than the intravenous route. While Group EM was more effective in the late period of postoperative, Group EMB was more effective in the early period. We concluded that epidural morphine was the most effective and preferred one.

Randomized controlled trial of bilateral intrapleural block in cardiac surgery

The aim of this study was to determine the efficacy of bilateral intrapleural block with bupivacaine as a preemptive analgesic for postoperative pain in coronary artery bypass graft surgery. In a double-blind prospective clinical trial, 70 patients were randomly divided into a bupivacaine group (20 mL bupivacaine 0.25% and 0.5 mL adrenaline 1/200,000 each side) and a control group (20.5 mL normal saline each side). Evaluation of the severity of pain was performed using the visual analog scale at 12 and 24 h after entering the intensive care unit and again during chest tube removal. Pain scores at 12 and 24 h after intensive care unit admission were significantly lower in the bupivacaine group. There were no side-effects related to intrapleural block, such as pneumothorax or emphysema. In coronary artery bypass graft candidates, preemptive analgesia with bilateral intrapleural block using bupivacaine provided relatively less painful conditions during the first 24 h after surgery, but it did not improve the clinical outcome.

Is Epidural Analgesia Necessary after Video-Assisted Thoracoscopic Lobectomy?

Most studies have shown that thoracic epidural analgesia reduces postoperative pain, but it carries potential risks. Recently, video-assisted thoracoscopic surgery has become an established technique that causes minimal postoperative pain. This report shows that thoracic epidural analgesia is not always necessary after video-assisted thoracoscopic lobectomy. From January to December 2007, 30 consecutive patients who underwent video-assisted thoracoscopic lobectomy were examined retrospectively. We analyzed the necessity for routine thoracic epidural analgesia. The continuous subcutaneous analgesia catheter for morphine (2 mg in 48 h) was removed from 15 patients on postoperative day 1, and from the other 15 on day 2. We administered loxoprofen sodium hydrate, diclofenac sodium suppository, pentazocine hydrochloride, and mexiletine hydrochloride for postoperative analgesia, as needed. The mean pain score was no more than 1.0. The maximum score was 3.0 on day 0, and 2.0 on day 14; subsequently, no pain score exceeded 2.0. The postoperative hospital stay was 8.7 ± 0.8 days. All patients made uneventful postoperative recoveries. There is no need for thoracic epidural analgesia after every video-assisted thoracoscopic lobectomy because our patients recovered with no serious complication. Less invasive surgical approaches should require simpler postoperative pain management.

A systematic review of randomized trials evaluating regional techniques for postthoracotomy analgesia

BACKGROUND

Thoracotomy induces severe postoperative pain and impairment of pulmonary function, and therefore regional analgesia has been intensively studied in this procedure. Thoracic epidural analgesia is commonly considered the "gold standard" in this setting; however, evaluation of the evidence is needed to assess the comparative benefits of alternative techniques, guide clinical practice and identify areas requiring further research.

METHODS

In this systematic review of randomized trials we evaluated thoracic epidural, paravertebral, intrathecal, intercostal, and interpleural analgesic techniques, compared to each other and to systemic opioid analgesia, in adult thoracotomy. Postoperative pain, analgesic use, and complications were analyzed.

RESULTS

Continuous paravertebral block was as effective as thoracic epidural analgesia with local anesthetic (LA) but was associated with a reduced incidence of hypotension. Paravertebral block reduced the incidence of pulmonary complications compared with systemic analgesia, whereas thoracic epidural analgesia did not. Thoracic epidural analgesia was superior to intrathecal and intercostal techniques, although these were superior to systemic analgesia; interpleural analgesia was inadequate.

CONCLUSIONS

Either thoracic epidural analgesia with LA plus opioid or continuous paravertebral block with LA can be recommended. Where these techniques are not possible, or are contraindicated, intrathecal opioid or intercostal nerve block are recommended despite insufficient duration of analgesia, which requires the use of supplementary systemic analgesia. Quantitative meta-analyses were limited by heterogeneity in study design, and subject numbers were small. Further well designed studies are required to investigate the optimum components of the epidural solution and to rigorously evaluate the risks/benefits of continuous infusion paravertebral and intercostal techniques compared with thoracic epidural analgesia.

Lumbar plexus blockade with ropivacaine for postoperative pain management in elderly patients undergoing urologic surgeries

BACKGROUND/AIMS

We evaluated the effectiveness and safety of lumbar plexus blockade with ropivacaine for postoperative pain relief in elderly patients undergoing flank incision for urological surgery.

METHODS

60 urological patients (>65 years old) were chosen randomly for paravertebral lumbar blockade. Postoperatively ropivacaine was used in group I (n = 30) and bupivacaine was administered in group II (n = 30) for lumbar plexus blockade. Heart rates, systolic and diastolic blood pressures, peripheral oxygen saturations, analgesia levels with visual analogue scales (VAS) were measured postoperatively at 5 and 30 min and 1, 3, 6, 8,and 12 h. Patient satisfaction scores and complications were recorded.

RESULTS

The hemodynamic parameters of the groups were in the normal ranges (p > 0.05). VAS were significantly decreased at 60 min in both groups (p < 0.05) and no important increase was observed during the first 8 h (p > 0.05). After the 8-hour measurement, analgesic was given to 7 patients in group I and 6 patients in group II (p < 0.05). There were no complications (p > 0.05). Patient satisfaction scores were found to be higher for all patients (p > 0.05).

CONCLUSION

In elderly patients, lumbar plexus blockade with ropivacaine can be a simple, safe and effective analgesic technique especially in the early postoperative period after urologic surgeries with flank incision.

The role of intrathecal drugs in the treatment of acute pain

Intrathecal opioids are widely used as useful adjuncts in the treatment of acute and chronic pain, and a number of non-opioid drugs show promise as analgesic drugs with spinal selectivity. In this review we examine the historical development and current use of intrathecal opioids and other drugs that show promise for treating pain in the perioperative period. The pharmacology and clinical use of intrathecal morphine and other opioids is reviewed in detail, including dosing guidelines for specific surgical procedures and the incidence and treatment of side effects associated with these drugs. Available data on the use of non-opioid drugs that have been tested intrathecally for use as analgesics are also reviewed. Evidence-based guidelines for dosing of intrathecal drugs for specific surgical procedures and for the treatment of the most common side effects associated with these drugs are presented.

Pain and Physical Function Are Similar Following Axillary, Muscle-Sparing vs Posterolateral Thoracotomy

STUDY OBJECTIVES

We set out to determine whether there is a difference in postoperative pain and recovery after the patient undergoes the axillary muscle-sparing incision (ie, muscle-sparing thoracotomy [MT]) vs the modified posterolateral incision (ie, posterolateral thoracotomy [PT]).

DESIGN

Analysis of a database originally collected to determine the effect of the timing of epidural analgesia on long-term outcome after thoracotomy.

SETTING

The Hospital of the University of Pennsylvania.

PATIENTS

Patients presenting for lobectomy, segmentectomy, or bilobectomy.

MEASUREMENTS

Pain, physical activity, and the extent that pain interfered with activities following major thoracotomy were prospectively assessed with standard questionnaires (ie, the brief pain inventory and the Medical Outcomes Study 36-item short form) on postoperative days 1 to 5, and at postoperative weeks 4, 8, 12, 24, 36, and 48 by a blinded research assistant. Perioperative care was standardized and included patient-controlled thoracic epidural analgesia until thoracostomy tube removal.

RESULTS

Eighty-two subjects underwent MT and 38 subjects underwent PT during the 16-month accrual period. There were no significant differences in demographics. Pain reported during hospitalization and after hospital discharge did not differ with respect to incision type (p > or = 0.17). Postoperative physical activity levels were significantly less than those reported preoperatively, with a trend toward better functioning in the MT groups after 8 weeks. Incision type did not predict complications, morbidity, or mortality.

CONCLUSIONS

When comparing patients who had undergone vertical, axillary, wholly MT to those who had undergone modified serratus muscle-sparing PT, postoperative differences in pain were not apparent. One should not anticipate reduced pain or more rapid overall recovery following MT, at least when epidural analgesia is used aggressively for perioperative pain control.

Comparison of Lumbar Epidural Tramadol and Lumbar Epidural Morphine for Pain Relief After Thoracotomy: A Repeated-Dose Study

OBJECTIVE

The purpose of this study was to compare lumbar epidural morphine and lumbar epidural tramadol with respect to onset and duration of analgesia, analgesic efficacy, and drug-related side effects after muscle-sparing thoracotomy.

DESIGN

Prospective, randomized, double-blind, clinical study.

SETTING

Single university hospital.

PARTICIPANTS

Forty patients who underwent elective muscle-sparing thoracotomy.

INTERVENTIONS

Before anesthesia induction, an epidural catheter was placed in the L2-3 or L3-4 interspace using the loss-of-resistance technique. On arrival at the intensive care unit, patients were randomized to receive doses of either 100 mg of tramadol (group T) or 4 mg of morphine (group M) via the lumbar epidural catheter. Each dose was diluted in 10 mL of normal saline. On awakening from anesthesia, if the patient's pain score on a 0- to 100-mm visual analog scale was above 40 mm, the initial epidural drug dose was administered. The initial injection in each case was taken as time 0. Subsequent pain scores above 40 mm were considered indications for epidural dosing; each patient was allowed 2 doses in the first 12 hours postoperatively and 2 more in the second 12 hours.

MEASUREMENTS AND MAIN RESULTS

The groups' analgesia onset times were similar, but duration of analgesia was significantly shorter in group T than in group M (p < 0.01). There were no differences between the groups with respect to pain scores at rest or during coughing at any of the time points investigated. Sedation scores were lower in group T than in group M at 1, 2, 3, 4, and 8 hours (p value range, 0.0001-0.05). Compared with group T, group M showed significantly greater drops in arterial oxygen tension from baseline at 3, 4, 8, and 12 hours (p value range, 0.0001-0.05). The group means for arterial carbon dioxide tension and respiratory rate were similar at all time points investigated.

CONCLUSION

The study revealed that the quality of analgesia achieved with repeated doses of lumbar epidural tramadol after muscle-sparing thoracotomy is comparable to that achieved with repeated doses of lumbar epidural morphine. Compared with morphine, lumbar epidural tramadol results in less sedation and a less-pronounced decrease in oxygenation.

Analgesic effects of interpleural bupivacaine with fentanyl for post-thoracotomy pain

OBJECTIVE

The analgesic effect of bupivacaine/fentanyl with epinephrine given interpleurally after thoracotomy was investigated in a randomized placebo and intravenous controlled study.

DESIGN

Prospective clinical study.

SETTING

University teaching hospital.

PARTICIPANTS

Sixty American Society of Anesthesiologists physical status II and III patients scheduled for posterolateral thoracotomy with general anesthesia.

INTERVENTIONS

Patients were randomly divided into 4 groups to receive either 0.5% bupivacaine/1.5 microg/kg of fentanyl with 5 microg/mL of epinephrine (n = 15, group IPBF), 0.5 % bupivacaine with 5 microg/mL of epinephrine (n = 15, group IPB), or saline (n = 15, group IPS) in a total volume of 15 to 20 mL in 60 seconds by an interpleural catheter placed at the end of surgery by direct vision. The same volume of bupivacaine 0.25% and 1.5 microg/kg of fentanyl with 5 microg/mL of epinephrine to group IPBF, bupivacaine 0.25% with 5 microg/mL of epinephrine to group IPB or saline to group IPS was injected through the interpleural catheter every 6 hours for 48 hours postoperatively. Intravenous fentanyl (n = 15, group IVF) and interpleural saline groups received 1.5 microg/kg of fentanyl intravenously at the first complaint of pain. All patients also received patient-controlled analgesia (PCA) with fentanyl for 48 hours postoperatively. Metamizol sodium was used as a rescue analgesic.

MEASUREMENTS AND MAIN RESULTS

Adequacy of pain relief was evaluated with the "Prince Henry Pain Scale" and visual analog pain scale. Fentanyl consumption via PCA and complications were evaluated for 48 hours. Visual analog scale scores were significantly higher in the interpleural saline group at 4 and 12 hours (6.6 +/- 1.2 and 5.0 +/- 2.1, respectively) postoperatively. Significantly more patients in the IPBF group had lower pain scores during coughing and deep breathing. Fentanyl consumption via PCA device was significantly higher in the intravenous fentanyl group (1,069 +/- 96.9 microg) than the interpleural groups (577.3 +/- 72.2 microg, 651.1 +/- 61.9 microg, and 601.0 +/- 22.6 microg in IPBF, IPB, and IPS groups, respectively).

CONCLUSION

It is concluded that total fentanyl consumption via PCA decreased in all interpleural groups, but pain during coughing and deep breathing was significantly reduced in only the interpleural bupivacaine/fentanyl with epinephrine group.

Impact of Acute Pain and Its Management for Thoracic Surgical Patients

Perioperative analgesia for thoracotomy has evolved in concert with increasing knowledge of the impact of pain on recovery, the origin of this pain, and new methods for treating it. Thoracic surgery is one of the few areas where there is more general agreement between surgeons and anesthesiologists as to the importance of aggressive pain management, often with an indwelling epidural catheter left in place until after thoracostomy tube removal. The reasons for this agreement is that it has become increasingly clear to both specialties that pain puts patients with decreased pulmonary reserve who undergo thoracotomy at greater risk for morbidity. Future studies need to examine drugs or drug combinations that can lead to further reductions in the often intense pain that patients receiving aggressive epidural analgesia still experience. Studies directed at finding interventions capable of reducing the rate of long-term postthoracotomy pain still need to be performed.

Shoulder function after thoracic surgery

Thoracic procedures are considered to be among the most painful surgical incisions and are associated with considerable postoperative pain and shoulder dysfunction, severely affecting mobility and activities of daily living. Improper patient positioning, muscle division, perioperative nerve injury, rib spreading, and consequent postoperative pain influence the patient's postoperative shoulder function and quality of life. To reduce access trauma and postoperative morbidity, various alternative modalities have been proposed to replace the standard PLT, including muscle-sparing techniques and VATS. Initial evaluations suggest that these alternatives are associated with significantly better postoperative shoulder function. Proper comparative studies using standardized questionnaires, objective evaluations, or quality-of-life assessments are scarce, however. Proper postoperative care, including early mobilization and effective physiotherapy, is a cornerstone in successful patient rehabilitation and rapid return to normal daily activities. Whether upper extremity exercises can contribute to improvement in postoperative shoulder function and the ability to perform activities of daily living needs to be studied further.

Epidural analgesia in gastrointestinal surgery

BACKGROUND

The ideal perioperative analgesia should provide effective pain relief, avoid the detrimental effects of the stress response, be simple to administer without the need for intensive monitoring, and have a low risk of complications.

METHODS

This review defines the physiological effects of epidural analgesia and assesses whether the available evidence supports its preferential use in gastrointestinal surgery. All papers studied were identified from a Medline search or selected by cross-referencing.

RESULTS

Epidural analgesia is associated with a shorter duration of postoperative ileus, attenuation of the stress response, fewer pulmonary complications, and improved postoperative pain control and recovery. It does not reduce anastomotic leakage, intraoperative blood loss, transfusion requirement, risk of thromboembolism or cardiac morbidity, or hospital stay compared with that after conventional analgesia in unselected patients undergoing gastrointestinal surgery. Thoracic epidural analgesia reduces hospital costs and stay in patients at high risk of cardiac or pulmonary complications.

CONCLUSIONS

Epidural analgesia enhances recovery after gastrointestinal surgery. The results support the development of structured regimens of early postoperative feeding and mobilization to exploit the potential for thoracic epidural analgesia to reduce hospital stay after gastrointestinal surgery.
