Abstract
BACKGROUND Intrathecal morphine provides effective analgesia for a range of operations. However, widespread implementation into clinical practice is hampered by concerns for potential side-effects. We undertook a systematic review, meta-analysis, and meta-regression with the primary objective of determining whether a threshold dose for non-pulmonary complications could be defined and whether an association could be established between dose and complication rates when intrathecal morphine is administered for perioperative or obstetric analgesia. METHODS We systematically searched the literature for randomised controlled trials comparing intrathecal morphine vs control in patients undergoing any type of surgery under general or spinal anaesthesia, or women in labour. Primary outcomes were rates of postoperative nausea and vomiting, pruritus, and urinary retention within the first 24 postoperative hours, analysed according to doses (1-100 μg; 101-200 μg; 201-500 μg; >500 μg), type of surgery, and anaesthetic strategy. Trials were excluded if doses were not specified. RESULTS Our analysis included 168 trials with 9917 patients. The rates of postoperative nausea and vomiting, pruritus, and urinary retention were significantly increased in the intrathecal morphine group, with an odds ratio (95% confidence interval) of 1.52 (1.29-1.79), P<0.0001; 6.11 (5.25-7.10), P<0.0001; and 1.73 (1.17-2.56), P=0.005, respectively. Meta-regression could not establish an association between dose and rates of non-pulmonary complications. There was no subgroup difference according to surgery for any outcome. The quality of evidence was low (Grading of Recommendations Assessment, Development, and Evaluation [GRADE] system). CONCLUSIONS Intrathecal morphine significantly increased postoperative nausea and vomiting, pruritus, and urinary retention after surgery or labour in a dose-independent manner.

Abstract
ABSTRACT Cardiac surgeries often result in significant postoperative pain, leading to considerable use of opioids for pain management. However, excessive opioid use can lead to undesirable side effects and chronic opioid use. This systematic review and meta-analysis aimed to evaluate whether preoperative intrathecal morphine could reduce postoperative opioid consumption in patients undergoing cardiac surgery requiring sternotomy. We conducted a systematic search of Cochrane, EMBASE, and MEDLINE databases from inception to May 2022 for randomized controlled trials that evaluated the use of intrathecal morphine in patients undergoing cardiac surgery. Studies that evaluated intrathecal administration of other opioids or combinations of medications were excluded. The primary outcome was postoperative morphine consumption at 24 h. Secondary outcomes included time to extubation and hospital length of stay. The final analysis included ten randomized controlled trials, with a total of 402 patients. The results showed that postoperative morphine consumption at 24 h was significantly lower in the intervention group (standardized mean difference -1.43 [-2.12, -0.74], 95% CI, P < 0.0001). There were no significant differences in time to extubation and hospital length of stay. Our meta-analysis concluded that preoperative intrathecal morphine is associated with lower postoperative morphine consumption at 24 h following cardiac surgeries, without prolonging the time to extubation. The use of preoperative intrathecal morphine can be considered part of a multimodal analgesic and opioid-sparing strategy in patients undergoing cardiac surgery.

Abstract
BACKGROUND Pain after cardiac surgery via median sternotomy can be difficult to treat, and if inadequately managed can lead to respiratory complications, prolonged hospital stays and chronic pain. OBJECTIVES To evaluate available literature and develop recommendations for optimal pain management after cardiac surgery via median sternotomy. DESIGN A systematic review using PROcedure-SPECific Pain Management (PROSPECT) methodology. ELIGIBILITY CRITERIA Randomised controlled trials and systematic reviews published in the English language until November 2020 assessing postoperative pain after cardiac surgery via median sternotomy using analgesic, anaesthetic or surgical interventions. DATA SOURCES PubMed, Embase and Cochrane Databases. RESULTS Of 319 eligible studies, 209 randomised controlled trials and three systematic reviews were included in the final analysis. Pre-operative, intra-operative and postoperative interventions that reduced postoperative pain included paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs), intravenous magnesium, intravenous dexmedetomidine and parasternal block/infiltration. CONCLUSIONS The analgesic regimen for cardiac surgery via sternotomy should include paracetamol and NSAIDs, unless contraindicated, administered intra-operatively and continued postoperatively. Intra-operative magnesium and dexmedetomidine infusions may be considered as adjuncts particularly when basic analgesics are not administered. It is not clear if combining dexmedetomidine and magnesium would provide superior pain relief compared with either drug alone. Parasternal block/surgical site infiltration is also recommended. However, no basic analgesics were used in the studies assessing these interventions. Opioids should be reserved for rescue analgesia. Other interventions, including cyclo-oxygenase-2 specific inhibitors, are not recommended because there was insufficient, inconsistent or no evidence to support their use and/or due to safety concerns.

Abstract
Pain after cardiac surgery is of moderate to severe intensity, which increases postoperative distress and health care costs, and affects functional recovery. Opioids have been central agents in treating pain after cardiac surgery for decades. The use of multimodal analgesic strategies can promote effective postoperative pain control and help mitigate opioid exposure. This Practice Advisory is part of a series developed by the Society of Cardiovascular Anesthesiologists (SCA) Quality, Safety, and Leadership (QSL) Committee's Opioid Working Group. It is a systematic review of existing literature for various interventions related to the preoperative and intraoperative pain management of cardiac surgical patients. This Practice Advisory provides recommendations for providers caring for patients undergoing cardiac surgery. This entails developing customized pain management strategies for patients, including preoperative patient evaluation, pain management, and opioid use-focused education as well as perioperative use of multimodal analgesics and regional techniques for various cardiac surgical procedures. The literature related to this field is emerging, and future studies will provide additional guidance on ways to improve clinically meaningful patient outcomes.

Abstract
Background To evaluate the analgesic efficacy and risk of low-to-medium dose intrathecal morphine (ITM) (i.e., ≤0.5 mg) following cardiac surgery. Methods Medline, Cochrane Library, Google scholar and EMBASE databases were searched from inception to February 2022. The primary outcome was pain intensity at postoperative 24 h, while the secondary outcomes included intravenous morphine consumption (IMC), extubation time, hospital/intensive care unit (ICU) length of stay (LOS), and ITM-associated side effects (e.g., respiratory depression). Subgroup analysis was performed on ITM dosage (low: <0.3 mg vs. medium: 0.3–0.5 mg). Results Fifteen RCTs involving 683 patients published from 1988 to 2021 were included. Pooled results showed significantly lower postoperative 24-h pain scores [mean difference (MD) = −1.61, 95% confidence interval: −1.98 to −1.24, p < 0.00001; trial sequential analysis: sufficient evidence; certainty of evidence: moderate] in the ITM group compared to the controls. Similar positive findings were noted at 12 (MD = −2.1) and 48 h (MD = −1.88). Use of ITM was also associated with lower IMC at 24 and 48 h (MD: −13.69 and −14.57 mg, respectively; all p < 0.05) and early tracheal extubation (i.e., 48.08 min). No difference was noted in hospital/ICU LOS, and nausea/vomiting in both groups, but patients receiving ITM had higher risk of pruritus (relative risk = 2.88, p = 0.008). There was no subgroup difference in IMC except a lower pain score with 0.3–0.5 mg than <0.3 mg at postoperative 24 h. Respiratory depression events were not noted in the ITM group. Conclusion Our results validated the analgesic efficacy of low-to-medium dose ITM for patients receiving cardiac surgery without increasing the risk of respiratory depression.

Abstract
Nonintubated thoracic surgery (NITS) has a good safety record in experienced hands, but has pitfalls for beginners. The main aim of NITS is to keep the patient under spontaneous respiration, avoiding adverse effects, such as hypoxemia, hypercapnia, panic attacks, and finally conversion to general anesthesia. In this paper, the safety aspects of anesthesia for NITS is discussed based on data from the literature and personnel clinical experiences.

Abstract
OBJECTIVES To examine the clinical efficacy of intrathecal morphine as postoperative analgesia for cervical laminoplasty. SUMMARY OF BACKGROUND DATA Patients who undergo posterior cervical spinal surgery frequently experience significant postoperative pain. Postoperative pain contributes to patient morbidity because of decreasing early voluntary mobilization and delayed rehabilitation. Intrathecal morphine is known to be a simple and effective analgesia. However, the effectiveness of intrathecal morphine for cervical spinal surgery has not yet been reported. METHODS Seventy-eight patients with cervical spondylotic myelopathy were divided into two groups prospectively, a diclofenac suppository (DS) group who received 50 mg diclofenac suppository at the end of the surgery, and an intrathecal morphine (ITM) group who were preoperatively administered 0.3 mg of morphine chloride, intrathecally, via a lumbar puncture. All patients underwent double-door laminoplasty of C3-6 or C3-7 level. Visual analog scale (VAS) of cervical pain, self-rating pain impression, supplemental analgesic usage, and complication rate were evaluated until the seventh postoperative day. RESULTS Thirty-one patients in the DS group and 32 patients in the ITM group were finally assessed. No baseline variable differences between the two groups were observed. The VAS was significantly lower in the ITM group at 4 h and 24 h until the seventh postoperative day. Self-rating pain impression was significantly better in the ITM group. No significant difference was observed in complication rate. CONCLUSIONS Intrathecal morphine was an effective and safe analgesic method for cervical laminoplasty in patients with cervical spondylotic myelopathy.

Abstract
STUDY OBJECTIVE To determine the risk factors of perioperative complications and the impact of intrathecal morphine (ITM) in major vascular surgery. DESIGN Retrospective analysis of a prospective cohort. SETTINGS Operating room, intensive care unit, and Postanesthesia Care Unit of a university hospital. MEASUREMENTS Data from 595 consecutive patients who underwent open abdominal aortic surgery between January 1997 and December 2011 were reviewed. Data were stratified into three groups based on the analgesia technique delivered: systemic analgesia (Goup SA), thoracic epidural analgesia (Group TEA), and intrathecal morphine (Group ITM). Preoperative patient characteristics, perioperative anesthetic and medical interventions, and major nonsurgical complications were recorded. MAIN RESULTS Patients managed with ITM (n=248) and those given thoracic epidural analgesia (n=70) required lower doses of intravenous (IV) sufentanil intraoperatively and were extubated sooner than those who received systemic analgesia (n=270). Total inhospital mortality was 2.9%, and 24.4% of patients experienced at least one major complication during their hospital stay. Intrathecal morphine was associated with a lower risk of postoperative morbidity (OR 0.51, 95% CI 0.28 - 0.89), particularly pulmonary complications (OR 0.54, 95% CI 0.31 - 0.93) and renal dysfunction (OR 0.52, 95% CI 0.29 - 0.97). Other predictors of nonsurgical complications were ASA physical status 3 and 4 (OR 1.94, 95% CI 1.07 - 3.52), preoperative renal dysfunction (OR 1.61, 95% CI 1.01 - 2.58), prolonged surgical time (OR 1.78, 95% CI 1.16 - 2.78), and the need for blood transfusion (OR 1.77, 95% CI 1.05 - 2.99). CONCLUSIONS This single-center study showed a decreased risk of major nonsurgical complications in patients who received neuraxial analgesia after abdominal aortic surgery.

Abstract
OBJECTIVES The present study compares the analgesic properties of intrathecal (IT group) and intravenous (IV group) sufentanil in postoperative pain relief. METHODS This randomized, single blinded study was performed on patients awaiting transhiatal esophagectomy. The patients were randomly allocated to receive sufentanil intrathecally or intravenously. Sufentanil consumption during the operation, pain score following the operation based on visual analog scale (VAS) and the morphine requirement for postoperative analgesia were assessed during the first 24 hours. RESULTS Fifty patients were divided in two groups. During the operation, the opioid requirement was higher in the IV group, whereas the morphine requirement during the first 24 hours after the operation was the same in both groups. The duration of effective postoperative analgesia was longer in patients in the IT group. VAS pain scores were significantly lower during the first 2 hours postoperatively in the IT group. The incidence of side effects such as nausea, vomiting, headache and respiratory depression was infrequent in both groups. CONCLUSIONS Preoperative IT sufentanil can be used as a booster to achieve rapid and effective analgesia not only during the operation but also during the immediate postoperative period.

Abstract
BACKGROUND Alpha2 adrenergic agonists have long been employed as analgesics and to sedate patients undergoing surgical procedures. In addition, their therapeutic response synergizes that elicited by opioids. Although this response is well known, the role of alpha2 agonists, such as clonidine, during various painful surgical procedures remains to be elucidated. The goal of our study was to evaluate the effects of the intrathecal administration of clonidine on postoperative pain control and time to extubation in patients undergoing coronary artery bypass grafting. METHODS Eighty-five patients undergoing coronary artery bypass grafting randomly received either an intrathecal injection of preservative free morphine 0.5 mg (MOR) or a combination of morphine 0.5 mg and clonidine 100 microg (CMC) before induction of anesthesia. Anesthesia was induced and maintained using a balanced anesthesia technique. Patients were transferred to the intensive care unit while intubated and weaned from mechanical ventilation following an established weaning protocol. Postoperative pain, opioid use within the first 24 hours, and time to extubation were used as primary outcome variables. Data were analyzed by a 2-tailed t test for continuous variables and Fisher exact test for nonparametric variables. RESULTS There were no demographic differences between the CMC and MOR groups. Postoperative pain, as assessed by a visual analog scale, was milder in the CMC group when compared with that of the MOR group (2.2+/-0.36 vs. 3.4+/-0.33, P<0.05). Similarly, patients in the CMC group required lower doses of morphine within 24 hours compared with the MOR group (2.02+/-0.36 vs. 6.47+/-0.49 mg, P<0.0001). Time to extubation was significantly shorter in patients receiving CMC than in those who received MOR (592+/-52 vs. 887+/-75 min, P<0.05). There was no mortality in either group. There was a trend for increased vasopressin use in the CMC group compared with the MOR group, although this was not statistically significant (P=0.07). CONCLUSIONS Addition of clonidine to neuraxial opioids improves the quality of analgesia postoperatively and expedites the process of weaning from mechanical ventilation. There were no serious adverse events in the cohort of the patients studied. However, the safety profile of this medication remains to be examined with a larger group of patients.
