Optimizing the use of ketamine to reduce chronic postsurgical pain in women undergoing mastectomy for oncologic indication: study protocol for the KALPAS multicenter randomized controlled trial. Trials 2024; 25:67. [PMID: 38243266 PMCID: PMC10797799 DOI: 10.1186/s13063-023-07884-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Accepted: 12/15/2023] [Indexed: 01/21/2024] Open
Abstract
BACKGROUND Mastectomies are commonly performed and strongly associated with chronic postsurgical pain (CPSP), more specifically termed postmastectomy pain syndrome (PMPS), with 25-60% of patients reporting pain 3 months after surgery. PMPS interferes with function, recovery, and compliance with adjuvant therapy. Importantly, it is associated with chronic opioid use, as a recent study showed that 1 in 10 patients continue to use opioids at least 3 months after curative surgery. The majority of PMPS patients are women, and, over the past 10 years, women have outpaced men in the rate of growth in opioid dependence. Standard perioperative multimodal analgesia is only modestly effective in prevention of CPSP. Thus, interventions to reduce CPSP and PMPS are urgently needed. Ketamine is well known to improve pain and reduce opioid use in the acute postoperative period. Additionally, ketamine has been shown to control mood in studies of anxiety and depression. By targeting acute pain and improving mood in the perioperative period, ketamine may be able to prevent the development of CPSP. METHODS Ketamine analgesia for long-lasting pain relief after surgery (KALPAS) is a phase 3, multicenter, randomized, placebo-controlled, double-blind trial to study the effectiveness of ketamine in reducing PMPS. The study compares continuous perioperative ketamine infusion vs single-dose ketamine in the postanesthesia care unit vs placebo for reducing PMPS. Participants are followed for 1 year after surgery. The primary outcome is pain at the surgical site at 3 months after the index surgery as assessed with the Brief Pain Inventory-short form pain severity subscale. DISCUSSION This project is part of the NIH Helping to End Addiction Long-term (HEAL) Initiative, a nationwide effort to address the opioid public health crisis. This study can substantially impact perioperative pain management and can contribute significantly to combatting the opioid epidemic. TRIAL REGISTRATION ClinicalTrials.gov NCT05037123.

[PMID: 37468443 DOI: 10.1111/aas.14307] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 06/22/2023] [Accepted: 06/23/2023] [Indexed: 07/21/2023]
Abstract
AIM We aimed to assess the beneficial and harmful effects of perioperative pain treatment with ketamine in patients undergoing spinal surgery. METHODS We searched Medline, Embase, and CENTRAL from inception until 15 February 2023 for randomised clinical trials comparing ketamine with placebo or no intervention in patients undergoing spinal surgery. The primary outcomes were cumulative opioid consumption at 24 h postoperatively and serious adverse events. We adhered to recommendations of the Cochrane Collaboration and performed meta-analysis, Trial Sequential Analysis (TSA) to assess the risks of random errors, risk of bias assessment to evaluate the risks of systematic errors, and used the Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS We included a total of 28 randomised clinical trials enrolling 2110 participants providing data for our pre-defined outcomes. Twenty-three trials enrolled adult participants and 5 trials enrolled paediatric participants. Three trials were at low risk of bias. Meta-analysis and TSA of trials including adults showed that ketamine versus placebo or no intervention seemed to reduce the cumulative 24-h opioid consumption (mean difference -17.57 mg; TSA-adjusted 95% confidence interval, -24.22 to -10.92; p < .01; low certainty of evidence), and there was no evidence of a difference of ketamine versus placebo or no intervention on the risk of serious adverse events (risk ratio 2.16; 96.7% confidence interval, 0.35 to 13.17; p = .36; very low certainty of evidence). CONCLUSION In adults undergoing spinal surgery, ketamine may reduce cumulative 24-h opioid consumption. Ketamine may increase the occurrence of serious adverse events, but the evidence was very uncertain.

Abstract
Background Postoperative cognitive dysfunction (POCD) is a common complication after anesthesia surgery, especially in older people, that can persist weeks or months after surgery as a short-term impairment of cognitive abilities, or even for a prolonged duration over years, potentially progressing into permanent cognitive dysfunction. However, the pathogenesis of POCD is not fully understood, and therefore an optimal solution for preventing POCD has yet to be established. Some studies have shown that intraoperative ketamine/esketamine reduces the incidence of POCD, but this remains controversial. Objectives We evaluated the effect of intraoperative subanesthetic doses of ketamine/esketamine versus no intervention in adults undergoing general anesthesia surgery on the incidence of POCD. Data Sources We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and searched the PubMed, Embase, Ovid, Cochrane, Scopus, and Web of Science databases for the MeSH terms 'ketamine', 'esketamine', and 'Postoperative Cognitive Complications' from database inception to 25 June 2023. Results We found no statistically significant difference in the incidence of POCD within 7 days for intraoperative subanesthetic dose of ketamine/esketamine compared with the control group [relative risk (RR) = 0.57, 95% confidence interval (CI): 0.32, 1.01], and the results from the subgroup analysis based on age (>60 years) also revealed that the difference was not statistically significant (RR = 0.49, 95% CI: 0.23, 1.04). Conclusion Compared with controls, intraoperative subanesthetic dose of ketamine/esketamine has no advantage in preventing POCD in patients, or in elderly patients. This study provides reference data for POCD research and clinical drug intervention strategies. Registration Prospective Register of Systematic Reviews (PROSPERO; registration number CRD42023401159).

Abstract
Identifying patients at risk for developing side effects secondary to intravenous patient-controlled analgesia (IV PCA) and making the necessary adjustments in pain management are crucial. We investigated the risk factors of discontinuing IV PCA due to side effects following general surgery; adult patients who received IV PCA after general surgery (2020-2022) were included. Data on postoperative pain intensity, PCA pain relief, side effects, continuity of PCA use, and PCA pump settings were collected from the records of the acute pain management team. The primary outcome was identifying the risk factors associated with PCA discontinuation due to side effects. Of the 8745 patients included, 94.95% used opioid-containing PCA, and 5.05% used non-steroidal anti-inflammatory drug (NSAID)-only PCA; 600 patients discontinued PCA due to side effects. Female sex (adjusted odds ratio [aOR] 3.31, 95% confidence interval [CI] 2.74-4.01), hepato-pancreatic-biliary surgery (aOR 1.43, 95% CI 1.06-1.94) and background infusion of PCA (aOR 1.42, 95% CI 1.04, 1.94) were associated with an increased likelihood of PCA discontinuation. Preoperative opioid use (aOR 0.49, 95% CI 0.28-0.85) was linked with a decreased likelihood of PCA discontinuation. These findings highlight the importance of individualized pain management, considering patient characteristics and surgical procedures.

Abstract
STUDY DESIGN Prospective randomized double-blind study. PURPOSE To assess the analgesic effects of the combination of a low-dose ketamine and dexmedetomidine (ketodex) infusion and compare it with that of fentanyl for postoperative analgesia after spine surgeries. OVERVIEW OF LITERATURE Adequate pain management following spine surgeries is crucial. Approximately 57% of patients experience inadequate pain control in the first 24 hours following elective spine surgery, which is attributable to the extensive soft tissue and muscle damage. METHODS The study included 60 patients graded American Society of Anesthesiologists I and II and scheduled for thoracolumbar spine surgery involving >3 vertebral levels. The patients were divided into two groups: group KD (ketodex) and group F (fentanyl). The primary objective was to compare the postoperative analgesic requirements among the groups. The secondary objectives included a comparison of the intraoperative anesthetic requirements, postoperative pain scores, hemodynamic parameters, side effects of the study drugs, and the duration of post-anesthesia care unit stay of both the groups. RESULTS Ketodex use prolonged the mean time to first rescue analgesia (22.00±2.30 hours vs. 11.69±3.02 hours, p <0.001) and reduced the requirement of rescue analgesics in the first 24 hours postoperatively compared to fentanyl use (70.00±8.16 μg vs. 113.31±36.65 μg, p =0.03). The intraoperative requirement of desflurane was comparable between the groups (p >0.05). The postoperative pain scores were significantly lower in the group KD than in group F at most timepoints (p <0.05). Patients in group KD had a shorter post-anesthesia care unit stay than group F did (p <0.001). CONCLUSIONS Low-dose ketodex could be a safe substitute for fentanyl infusion when employed as an anesthetic adjuvant for patients undergoing thoracolumbar spine surgeries involving >3 vertebral levels to achieve prolonged analgesia without any opioidrelated side effects.

BRAZILIAN JOURNAL OF ANESTHESIOLOGY (ELSEVIER) 2023; 73:165-170. [PMID: 34332956 PMCID: PMC10068526 DOI: 10.1016/j.bjane.2021.07.015] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Revised: 07/12/2021] [Accepted: 07/17/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND Opioids are the cornerstone in managing postoperative pain; however, they have many side effects. Ketamine and Magnesium (Mg) are NMDA receptor antagonists used as adjuvant analgesics to decrease postoperative opioid consumption. OBJECTIVE We assumed that adding Mg to ketamine infusion can improve the intraoperative and postoperative analgesic efficacy of ketamine infusion alone in cancer breast surgeries. METHODS Ninety patients aged between 18 and 65 years and undergoing elective cancer breast surgery were included in this prospective randomized, double-blind study. Group K received ketamine 0.5.ßmg.kg...1 bolus then 0.12.ßmg.kg...1.h...1 infusion for the first 24.ßhours postoperatively. Group KM: received ketamine 0.5.ßmg.kg...1 and Mg sulfate 50.ßmg.kg...1, then ketamine 0.12.ßmg.kg...1.h...1 and Mg sulfate 8.ßmg.kg...1.h...1 infusions for the first 24.ßhours postoperative. The primary outcome was the morphine consumption in the first 24.ßhours postoperative, while the secondary outcomes were: intraoperative fentanyl consumption, NRS, side effects, and chronic postoperative pain. RESULTS Group KM had less postoperative opioid consumption (14.12.ß...ß5.11.ßmg) than Group K (19.43.ß...ß6.8.ßmg). Also, Group KM had less intraoperative fentanyl consumption. Both groups were similar in postoperative NRS scores, the incidence of side effects related to opioids, and chronic neuropathic pain. CONCLUSION Adding Mg to ketamine infusion can safely improve intraoperative and postoperative analgesia with opioid-sparing effect in cancer breast surgery.

Abstract
Background Subanesthetic doses of ketamine have been shown to improve the efficacy of opioids, increase pain control, and exemplify opioid-sparing effects when used as postoperative analgesia for adults. Objectives To determine, for surgical patients, the impact of IV ketamine infusions on opioid use in hospital, overall and within 24 h before discharge, as well as pain scores. Methods A retrospective matched cohort study was conducted, in which surgical patients exposed to ketamine were compared with those not exposed to ketamine, among admissions from January 1, 2018, to February 28, 2020. Patients were matched for age, surgical service, and sex. Results A total of 104 patients were included in the study. Overall, there was no significant difference in mean total opioid use in hospital for patients exposed and not exposed to ketamine (171.7 mg versus 115.5 mg oral morphine equivalent [OME], p = 0.09), nor was there any difference in opioid use in the 24 h before discharge (28.2 mg versus 18.2 mg OME, p = 0.14). Patient-reported pain scores did not differ between groups. More patients in the ketamine group experienced hallucinations than in the group not exposed to ketamine (5 versus 0, p = 0.024). Conclusions Overall, subanesthetic doses of IV ketamine used postoperatively in surgical patients did not decrease opioid use or patient-reported pain. More patients who received ketamine had documented hallucinations. These results will help guide postoperative analgesia practice and strategies to reduce opioid use.

Abstract
Emergence delirium (ED) is a temporary condition associated with a patient awakening from an anesthetic and/or adjunct agent (e.g., sedatives and analgesics). During the condition, patients risk harming themselves or staff by engaging in dangerous behavior, which may include thrashing, kicking, punching, and attempting to exit the bed/table.
A multidisciplinary team at Veterans Affairs Pittsburgh Healthcare System (VAPHS) developed and implemented a multicomponent intervention to reduce the severity and occurrence of ED. The intervention consists of a training component and 21 clinical components. The 21 clinical components are implemented on a patient-by-patient basis and include routine screening for risk factors, enhanced communication among staff, adjusting the environment, following a specific medication strategy, and application of manual restraint (hands-on). The authors provide 15 online Supplemental Materials (S1–S15) to promote replication of the intervention.
To our knowledge, this is the first manuscript that describes this type of multicomponent intervention in sufficient detail to allow others to replicate it. Following implementation of the intervention at VAPHS, perioperative staff reported that they observed a substantial reduction in the occurrence and severity of ED, ED-related patient and staff injuries, and ED-related loss of intravenous access and airway patency. Despite staff’s reported success of the intervention, rigorous research is needed to evaluate the efficacy of the intervention.

Abstract
Purpose This study aims to investigate the effects of the different doses of esketamine on postoperative quality of recovery in patients undergoing modified radical mastectomy. Methods Ninety-nine female patients were randomly allocated to three groups: the low-dose esketamine group (group E1) (0.5 mg/kg loading, 2 µg/kg/h infusion), the high-dose esketamine group (group E2) (0.5 mg/kg loading, 4 µg/kg/h infusion), the control group (group C) (received normal saline). The primary outcome was the quality of recovery-15 (QoR-15) scores on postoperative day 1 (POD1) and days 3 (POD3). The secondary outcomes were the sleep quality scores on POD1, bispectral index (BIS) value at 10, 30, and 60 min after operation, numeric rating scale (NRS) pain scores within 24 h after surgery, nausea, vomiting, drowsiness, nightmare, and intraoperative awareness. Results The total QoR-15 scores were higher in group E1 and group E2 than in group C on POD1 and POD3 (P<0.05). The sleep quality scores on POD1 and BIS value at 10, 30, and 60 min after operation were higher in group E1 and group E2 than in group C (P<0.05). The NRS pain scores at 2, 4 and 6 h after surgery in group E1 and at 2, 4, 6, 12 and 24 h after surgery in group E2 were lower than in group C (P<0.05). The NRS pain scores at 6, 12 and 24 h after surgery in group E2 were lower than in group E1 (P<0.05). The incidence of drowsiness was higher in group E1 and group E2 than in group C (P<0.05). Conclusion Esketamine infusion improved to some extent the quality of recovery on POD1 and POD3 in patients undergoing modified radical mastectomy, especially 4 µg/kg/h esketamine was better, but the BIS value and incidence of drowsiness were significantly increased.

Abstract
Supplemental Digital Content is Available in the Text. Patients undergoing spinal surgery are at high risk of acute and persistent postoperative pain. Therefore, adequate pain relief is crucial. This systematic review aimed to provide answers about best-proven postoperative analgesic treatment for patients undergoing lumbar 1- or 2-level fusions for degenerative spine diseases. We performed a search in PubMed, Embase, and The Cochrane Library for randomized controlled trials. The primary outcome was opioid consumption after 24 hours postoperatively. We performed meta-analyses, trial sequential analyses, and Grading of Recommendations assessment to accommodate systematic errors. Forty-four randomized controlled trials were included with 2983 participants. Five subgroups emerged: nonsteroidal anti-inflammatory drugs (NSAIDs), epidural, ketamine, local infiltration analgesia, and intrathecal morphine. The results showed a significant reduction in opioid consumption for treatment with NSAID (P < 0.0008) and epidural (P < 0.0006) (predefined minimal clinical relevance of 10 mg). Concerning secondary outcomes, significant reductions in pain scores were detected after 6 hours at rest (NSAID [P < 0.0001] and intrathecal morphine [P < 0.0001]), 6 hours during mobilization (intrathecal morphine [P = 0.003]), 24 hours at rest (epidural [P < 0.00001] and ketamine [P < 0.00001]), and 24 hours during mobilization (intrathecal morphine [P = 0.03]). The effect of wound infiltration was nonsignificant. The quality of evidence was low to very low for most trials. The results from this systematic review showed that some analgesic interventions have the capability to reduce opioid consumption compared with control groups. However, because of the high risk of bias and low evidence, it was impossible to recommend a “gold standard” for the analgesic treatment after 1- or 2-level spinal fusion surgery.

Perioperative Low-Dose Ketamine for Postoperative Pain Management in Spine Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. Pain Res Manag 2022; 2022:1507097. [PMID: 35401887 PMCID: PMC8989618 DOI: 10.1155/2022/1507097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2021] [Accepted: 02/22/2022] [Indexed: 12/03/2022]
Abstract
Objective Although low-dose ketamine has been shown to be generally beneficial in terms of pain control in a variety of major surgery, there is no consensus regarding the effectiveness of supplemental ketamine analgesic use exclusively in spine surgery. The objective of this systematic review and meta-analysis of randomized controlled trials (RCTs) was to assess the efficacy and safety of perioperative low-dose ketamine for pain management and analgesic consumption in patients undergoing spine surgery. Methods A comprehensive literature search was performed for relevant studies using PubMed, EMBASE, Web of Science, and Cochrane Library. Patients who received perioperative low-dose ketamine were compared to the control group in terms of postoperative pain intensity, opioid consumption, and adverse events. Patients were further categorized by ages and administration times for subgroup analysis. Results A total of 30 RCTs comprising 1,865 patients undergoing elective spine surgery were included. Significantly lower pain intensity and less opioid consumption at 12 h, 24 h, and 48 h postoperatively and lower incidence of postoperative nausea and vomiting (PONV) were observed in the ketamine group (all P < 0.05). There was no significant difference of central nervous system (CNS) adverse events between groups. However, different efficacy of low-dose ketamine was detected when patients were categorized by ages and administration times. Conclusion Perioperative low-dose ketamine demonstrated analgesic and morphine-sparing effect with no increased adverse events after spine surgery. However, this effect was not significant in pediatric patients. Only postoperative or intraoperative and postoperative administration could prolong the analgesic time up to 48 h postoperatively. Further studies should focus on the optimal protocol of ketamine administration and its effect on old age participants.

Abstract
Pain following brain surgery can compromise the result of surgery. Several pharmacological interventions have been used to prevent postoperative pain in adults undergoing brain surgery. Pain following craniotomy is considered to be moderate to severe during the first two post-operative days. Opioids have been historically the mainstay and are the current prominent strategy for pain treatment. They produce analgesia but may alter respiratory, cardiovascular, gastrointestinal, and neuroendocrine functions. All these side effects may affect the normal postoperative course of craniotomy by affecting neurological function and increasing intracranial pressure. Therefore, their use in neurosurgery is limited, and opioids are used in case of strict necessity or as rescue medication. In addition to opioids, drugs with differing mechanisms of actions target pain pathways, resulting in additive and/or synergistic effects. Some of these agents include acetaminophen/non-steroidal anti-inflammatory drugs (NSAIDs), alpha-2 agonists, NMDA receptor antagonists, gabapentinoids, and local anesthesia techniques. Multimodal analgesia should be a balance between adequate analgesia and less drug-induced sedation, respiratory depression, hypercapnia, nausea, and vomiting, which may increase intracranial pressure. Non-opioid analgesics can be an useful pharmacological alternative in multimodal regimes to manage post-craniotomy pain. This narrative review aims to outline the current clinical evidence of multimodal analgesia for post craniotomy pain control.

Abstract
Evidence-based standardization of the perioperative management of patients undergoing complex spine surgery can improve outcomes such as enhanced patient satisfaction, reduced intensive care and hospital length of stay, and reduced costs. The Society for Neuroscience in Anesthesiology and Critical Care (SNACC) tasked an expert group to review existing evidence and generate recommendations for the perioperative management of patients undergoing complex spine surgery, defined as surgery on 2 or more thoracic and/or lumbar spine levels. Institutional clinical management protocols can be constructed based on the elements included in these clinical practice guidelines, and the evidence presented.

Abstract
Background Persistent pain and opioid use can be devastating after cytoreductive surgery (CRS) and hyperthermic intraoperative chemotherapy (HIPEC). Methods We conducted a retrospective study to investigate the impact of ketamine use on postoperative complications and persistent and chronic pain after CRS-HIPEC. Results Ketamine reduced perioperative opioid use before and after implementation of recovery after surgery programs. Ketamine did not impact the formation of persistent and chronic pain formation and long-term opioid use. Postoperative complications and postoperative re-operations were independent predictors of persistent pain. Interestingly, the risk of having a complication was increased by 1% for every doubling in opioids used intraoperatively. Conclusion Ketamine use reduces perioperative opioid consumption in patients undergoing CRS-HIPEC, but it is not associated with improvements in long-term opioid use and chronic pain.

Abstract
BACKGROUND There has been a growing interest in the use of ketamine following orthopedic surgeries. We hypothesized that low dose intravenous ketamine during surgery would help in mobilization following total knee replacement (TKR) in oncology patients as assessed by the timed to up and go (TUG) test at 72.áhours post-surgery. Our secondary objectives were to compare the opioid requirement at the end of 72.áhours, pain scores, satisfaction with pain management, adverse effects, range of joint movement achieved in the post-operative period and the functional recovery at the end of 1 month. METHODS After the ethics commitee approval, registration of the trial with the Clinical Trial Registry - India (CTRI), and informed consent, this double-blinded trial was conducted. Using computer generated randomization chart, an independent team randomized the patients into ketamine group which received at induction, a ketamine bolus dose of 0.5.ámg.kg-1 before the incision followed by 10.á..g.kg-1min-1 infusion which was maintained intraoperatively till skin closure and the saline group received an equivalent volume of saline. Postoperatively, patient controlled morphine pumps were attached and the pain score with morphine usage were recorded for 72.áhours. The TUG tests and range of motion were assessed by the physiotherapists until 72.áhours. RESULTS Fifty-two patients were enrolled in the trial. Demographics were comparable. No significant intraoperative hemodynamic changes and post-operative adverse events were noted between the groups. A decrease in the TUG test, along with decreased opioid usage with a better range of movements was noted in the ketamine group, but this was not statistically significant. Day of discharge, patient satisfaction score, and functional recovery assessed by Oxford Knee Score (OKS) were comparable between the groups. CONCLUSION In conclusion, low dose intraoperative ketamine infusion does not provide clinical benefit in perioperative pain management and postoperative rehabilitation following total knee endoprosthetic replacement in oncology.

Abstract
PURPOSE Ketamine's inhibitory action on the N-methyl-D-aspartate receptor and anti-inflammatory effects may provide beneficial immunomodulation in cancer surgery. We investigated the effect of subanesthetic-dose ketamine as an adjunct to desflurane anesthesia on natural killer (NK) cell activity and inflammation in patients undergoing colorectal cancer surgery. METHODS A total of 100 patients were randomly assigned to a control or ketamine group. The ketamine group received a bolus of 0.25 mg·kg-1 ketamine five minutes before the start of surgery, followed by an infusion 0.05 mg·kg-1·hr-1 until the end of surgery; the control group received a similar amount of normal saline. We measured NK cell activity and proinflammatory cytokines (interleukin-6 [IL-6] and tumour necrosis factor-α [TNF-α]) before surgery and one, 24, and 48 hr after surgery. C-reactive protein (CRP) was measured before surgery and one, three, and five days after surgery. Carcinoembryonic antigen and cancer recurrence/metastasis were assessed two years after surgery. RESULTS The NK cell activity was significantly decreased after surgery in both groups, but the change was not different between groups in the linear mixed model analysis (P = 0.47). Changes in IL-6, TNF-α, CRP, and carcinoembryonic antigen levels were not different between groups (P = 0.27, 0.69, 0.99, and 0.97, respectively). Cancer recurrence within 2 years after surgery was similar between groups (10% vs 8%, P = 0.62). CONCLUSIONS Intraoperative low-dose ketamine administration did not convey any favourable impacts on overall postoperative NK cell activity, inflammatory responses, and prognosis in colorectal cancer surgery patients.

Abstract
Ketamine, an N-methyl-D-aspartate receptor antagonist, is widely known as a dissociative anesthetic and phencyclidine derivative. Due to an undesirable adverse event profile when used as an anesthetic it had widely fallen out of human use in favor of more modern agents. However, it has recently been explored for several other indications such as treatment resistant depression and chronic pain. Several recent studies and case reports compiled here show that ketamine is an effective analgesic in chronic pain conditions including cancer-related neuropathic pain. Of special interest is ketamine's opioid sparing ability by counteracting the central nervous system sensitization seen in opioid induced hyperalgesia. Furthermore, at the sub-anesthetic concentrations used for analgesia ketamine's safety and adverse event profiles are much improved. In this article, we review both the basic science and clinical evidence regarding ketamine's utility in chronic pain conditions as well as potential adverse events.

Abstract
BACKGROUND Severe pain often accompanies major spine surgery. Opioids are the cornerstone of postoperative pain management but their use can be limited by numerous side effects. Several studies claim that adjuvant treatment with intravenous (IV) ketamine reduces opioid consumption and pain after back surgery. However, the exact role of ketamine for this indication is yet to be elucidated. We compared 2 different doses of S-ketamine with placebo on postoperative analgesic consumption, pain, and adverse events in adult, opioid-naïve patients after lumbar fusion surgery. METHODS One hundred ninety-eight opioid-naïve patients undergoing lumbar spinal fusion surgery were recruited to this double-blind trial and randomly assigned into 3 study groups: Group C (placebo) received a preincisional IV bolus of saline (sodium chloride [NaCl] 0.9%) followed by an intraoperative IV infusion of NaCl 0.9%. Both groups K2 and K10 received a preincisional IV bolus of S-ketamine (0.5 mg/kg); in group K2, this was followed by an intraoperative IV infusion of S-ketamine (0.12 mg/kg/h), while in group K10, it was followed by an intraoperative IV infusion of S-ketamine (0.6 mg/kg/h). Postoperative analgesia was achieved by an IV patient-controlled analgesia (IV PCA) device delivering oxycodone. The primary end point was cumulative oxycodone consumption at 48 hours after surgery. The secondary end points included postoperative pain up to 2 years after surgery, adverse events, and level of sedation and confusion in the immediate postoperative period. RESULTS The median [interquartile range (IQR)] cumulative oxycodone consumption at 48 hours was 154.5 [120] mg for group K2, 160 [109] mg for group K10, and 178.5 [176] mg for group C. The estimated difference was -24 mg between group K2 and group C (97.5% confidence interval [CI], -73.8 to 31.5; P = .170) and -18.5 mg between group K10 and C (97.5% CI, 78.5-29.5; P = .458). There were no significant differences between groups.Postoperative pain scores were significantly lower in both ketamine treatment groups at the fourth postoperative hour but not later during the 2-year study period.The higher ketamine dose was associated with more sedation. Otherwise, differences in the occurrence of adverse events between study groups were nonsignificant. CONCLUSIONS Neither a 0.12 nor a 0.6 mg/kg/h infusion of intraoperative IV S-ketamine was superior to the placebo in reducing oxycodone consumption at 48 hours after lumbar fusion surgery in an opioid-naïve adult study population. Future studies should assess ketamine's feasibility in specific study populations who most benefit from reduced opioid consumption.

Abstract
Objective Recent research has focused on the use of N-methyl-D-aspartate (NMDA) receptor antagonists for pain management. Several drugs are known to have this action, including ketamine, which exerts its main analgesic effect through NMDA receptor antagonism. This study aimed to evaluate the effect of low-dose ketamine infusion on opioid exposure for patients undergoing myomectomy surgery under general anaesthesia. Methods A total of 70 women were included in this prospective double-blind trial study. The patients included in this study were American Society of Anaesthesiologists physical status I-II, aged between 18 and 50 years and scheduled for laparotomy myomectomy surgery. Patients were randomised to receive either a bolus of 0.2 mg kg-1 of ketamine followed by a continuous infusion of 0.2 mg kg-1 hr-1 during the operation or a placebo of normal saline. Both groups also received morphine as needed for pain relief. The primary outcome was the total amount of morphine used during the intraoperative and postoperative periods. Intraoperative and postoperative mean blood pressure, heart rate and postoperative visual analogue scale for pain were assessed. Results Total mean morphine consumption was significantly lower in the ketamine group than in the control group (26±3.5 mg vs. 34.7±3.3 mg, respectively, p<0.05). However, there were no statistical differences between the groups regarding haemodynamics, postoperative pain score and complications. Conclusion The use of ketamine in low infusion doses intraoperatively during an elective myomectomy procedure produced an opioid-sparing effect by reducing perioperative morphine consumption without significant side effects.

Abstract
Objective: Acute pain management is fundamental in prehospital trauma care. Early pain control may decrease the risk of developing post-traumatic stress disorder (PTSD) and chronic pain. Fentanyl and ketamine are frequently used off-label, but there is a paucity of comparative data to guide decision-making about treatment of prehospital severe, acute pain. This trial will determine whether the addition of single dose of intranasal ketamine to fentanyl is more effective for the treatment of acute traumatic pain than administration of fentanyl alone.Methods: This two-part study consists of prehospital and 90-day follow-up components (NCT02866071). The prehospital trial is a blinded, randomized, controlled trial of adult men (age 18-65 years) rating pain ≥7/10 after an acute traumatic injury of any type. Women will be excluded due to inability to confirm pregnancy status and unknown fetal risk. Paramedics will screen patients receiving standard of care fentanyl and, after obtaining standard informed consent, administer 50 mg intranasal ketamine or matching volume saline as placebo. Upon emergency department (ED) arrival, research associates will serially assess pain, concomitant treatments, and adverse side effects. Enrolled subjects will be approached for consent to participate in the 90-day follow-up study to determine rates of PTSD and chronic pain development. The primary outcome of the prehospital study is reduction in pain on the Verbal Numerical Rating Scale between baseline and 30-minutes after study drug administration. The proportion achieving a reduction of ≥2-points will be compared between study arms using a Chi-square test. Secondary outcomes of the prehospital trial include reduction in reported pain at the time of ED arrival and at 30 minutes intervals for up to three hours of ED care, the incidence of adverse events, and additional opiate requirements prior to ED arrival and within the first three hours of ED care. The outcomes in the follow-up study are satisfaction with life and development of PTSD or chronic pain at 90 days after injury. An intention-to-treat approach will be used.Conclusion: These studies will test the hypotheses that ketamine plus fentanyl, when compared to fentanyl alone, effectively manages pain, decreases opiate requirements, and decreases PTSD at 90 days.

Abstract
BACKGROUND Multimodal analgesia protocols are becoming a common part of enhanced recovery pathways after colorectal surgery. However, few protocols include a robust intraoperative component in addition to pre-operative and post-operative analgesics. METHOD A prospective cohort study was performed in an urban teaching hospital in patients undergoing minimally invasive colorectal surgery before and after implementation of a multimodal analgesia protocol consisting of pre-operative (gabapentin, acetaminophen, celecoxib), intraoperative (lidocaine and magnesium infusions, ketorolac, transversus abdominis plane block), and post-operative (gabapentin, acetaminophen, celecoxib) opioid-sparing elements. The main outcome measure was use of morphine equivalents in the first 24-h post-operative period. RESULTS The study cohort (n = 71) included 41 patients before and 30 patients after implementation of a multimodal analgesia protocol. Mean age of the entire study cohort was 47 ± 19.7 years and 46% were male. Patients undergoing surgery post-multimodal analgesia vs. pre-multimodal analgesia had significantly lower use of IV morphine equivalents in first 24-h post-operative period (5.8 ± 6.4 mg vs. 22.8 ± 21.3 mg; p = 0.005) and first 48-h post-operative period (7.6 ± 9.4 mg vs. 42 ± 52.9 mg; p = 0.0008). This reduction in IV morphine equivalent use post-multimodal analgesia was coupled with improved pain scores in the post-operative period. Post-operative hospital length of stay, post-operative ileus, and overall complications were not significantly different between groups. CONCLUSIONS Multimodal analgesia incorporating pre-operative, intraoperative, and post-operative opioid-sparing agents is an effective method for reducing perioperative opioid utilization and pain after minimally invasive colorectal surgery.

Abstract
BACKGROUND Patients with spinal fusion often have opioid tolerance and chronic pain, which makes it difficult to control postoperative pain. In this double-blind, randomized, prospective study, we assessed the safety and efficacy of intravenous low-dose ketamine for the treatment of pain in patients undergoing the lumbar spinal fusion. METHODS This randomized, prospective, double-blind and placebo-controlled study was approved via the hospital institutional review committee. Patients were registered with signed written consent. All the floor nurses, recovery room and surgeons, patients, statisticians as well as research assistants were unaware of the grouping. The patients were randomly divided into ketamine group and control group by random number table. Nausea, vomiting or vomiting, the intensity of pain, adverse events, cumulative morphine consumption, as well as the amount of extra antiemetics or analgesics were evaluated at 6 hours, 12 hours, 24 hours, 36 hours, and 48 hours after the operation. P < .05 was considered to be the statistically significant. The Statistical Package for the software of Social Sciences 20.0 was utilized for statistical analysis. CONCLUSIONS For the present trial, we assumed that intravenous ketamine could improve the satisfaction of patient by reducing the total consumption of morphine equivalent and the pain scores. TRIAL REGISTRATION This study protocol was registered in Research Registry (researchregistry5896).

Abstract
Adequate analgesia is known to improve outcomes after spine surgery. Despite recent attention highlighting the negative effects of narcotics and their addiction potential, opioids have been the mainstay of management for providing analgesia following spine surgeries. However, side effects including hyperalgesia, tolerance, and subsequent dependence restrict the generous usage of opioids. Multimodal analgesia regimens acting through different mechanisms offer significant opioid sparing and minimize the side effects of individual drugs. Hence, they are being increasingly incorporated into enhanced recovery protocols. Multimodal analgesia includes drugs such as N-methyl-D-aspartate antagonists, nonsteroidal anti-inflammatory drugs and membrane-stabilizing agents, neuraxial opioids, local anesthetic infiltration, and fascial compartment blocks. Analgesia started before the painful stimulus, termed preemptive analgesia, facilitates subsequent pain management. Both nonsteroidal anti-inflammatory drugs and neuraxial analgesia have been conclusively shown to reduce opioid requirements after spine surgery, and there is a resurgence of interest in the use of low-dose ketamine or methadone. Neuraxial narcotics offer enhanced analgesia for a longer duration with lower dosage and side effect profiles compared with systemic opioid administration. Fascial compartment blocks are increasingly used as they provide effective analgesia with fewer adverse effects. In this narrative review, we will discuss multimodality analgesic regimens incorporating opioid-sparing adjuvants to manage pain after spine surgery.

Abstract
OBJECTIVE In the context of the current opioid epidemic, there has been a renewed interest in the use of ketamine as an analgesic agent. METHODS We reviewed ketamine analgesia. RESULTS Ketamine is well-known as an antagonist for N-methyl-D-aspartate receptors. In addition, it can regulate the function of opioid receptors and sodium channels. Ketamine also increases signaling through α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors. These myriad of molecular and cellular mechanisms are responsible for a number of pharmacological functions including pain relief and mood regulation. Clinically, a number of studies have investigated the role of ketamine in the setting of acute and chronic pain, and there is evidence that ketamine can provide analgesia in a variety of pain syndromes. DISCUSSION In this review, we examined basic mechanisms of ketamine and its current clinical use and potential novel use in pain management.

Does Sub-Anesthetic Ketamine Provide Postoperative Analgesia for Third Molar Surgery? J Oral Maxillofac Surg 2019; 77:2452-2464.

Abstract
PURPOSE Despite ketamine's effectiveness as an anesthetic and its known analgesic properties, the role of ketamine in postoperative pain after third molar surgery remains unclear. Therefore, this study aimed to investigate whether patients undergoing third molar surgery who received a sub-anesthetic preoperative dose of intravenous ketamine would experience less postoperative pain. MATERIALS AND METHODS We implemented a randomized, double-blinded, placebo-controlled trial. The study sample consisted of participants undergoing third molar surgery with procedural sedation anesthesia. Participants were randomized to receive a preoperative intravenous dose of ketamine or placebo, as predictor variables. The primary outcome variable was postoperative pain intensity determined by a 10-point visual analog scale at 6-hour intervals over a period of 48 hours. The secondary outcome variable was the quantity of postoperative non-opioid and opioid consumption. Other variables included the extent and difficulty of surgery performed, patient satisfaction, gender, and age. Data analysis involved descriptive statistics, multivariate analysis, and regression analysis. The P value was set at .05. RESULTS A total of 134 participants were randomly enrolled into either the ketamine group (n = 74, 55.2%) or placebo group (n = 60, 44.8%). No statistically significant differences in the distribution of study variables were found between the groups. A small yet statistically significant (P < .05) difference was noted in the median pain score at 6 hours postoperatively, with the ketamine group experiencing more pain. However, no further differences were detected at any postoperative time between the 2 groups. Similar results were obtained after adjusting for age, gender, and surgical difficulty. No difference in the amount of postoperative non-opioid or opioid medication use was found between the 2 groups. CONCLUSIONS This study did not find evidence that a preoperative sub-anesthetic dose of ketamine could reduce pain after third molar surgery or have any effects on non-opioid or opioid analgesic consumption. Nevertheless, ketamine remains a valuable option among sedation medications for oral and maxillofacial surgeons.

Abstract
BACKGROUND Inadequate pain management after surgery increases the risk of postoperative complications and may predispose for chronic postsurgical pain. Perioperative ketamine may enhance conventional analgesics in the acute postoperative setting. OBJECTIVES To evaluate the efficacy and safety of perioperative intravenous ketamine in adult patients when used for the treatment or prevention of acute pain following general anaesthesia. SEARCH METHODS We searched CENTRAL, MEDLINE and Embase to July 2018 and three trials registers (metaRegister of controlled trials, ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP)) together with reference checking, citation searching and contact with study authors to identify additional studies. SELECTION CRITERIA We sought randomised, double-blind, controlled trials of adults undergoing surgery under general anaesthesia and being treated with perioperative intravenous ketamine. Studies compared ketamine with placebo, or compared ketamine plus a basic analgesic, such as morphine or non-steroidal anti-inflammatory drug (NSAID), with a basic analgesic alone. DATA COLLECTION AND ANALYSIS Two review authors searched for studies, extracted efficacy and adverse event data, examined issues of study quality and potential bias, and performed analyses. Primary outcomes were opioid consumption and pain intensity at rest and during movement at 24 and 48 hours postoperatively. Secondary outcomes were time to first analgesic request, assessment of postoperative hyperalgesia, central nervous system (CNS) adverse effects, and postoperative nausea and vomiting. We assessed the evidence using GRADE and created a 'Summary of findings' table. MAIN RESULTS We included 130 studies with 8341 participants. Ketamine was given to 4588 participants and 3753 participants served as controls. Types of surgery included ear, nose or throat surgery, wisdom tooth extraction, thoracotomy, lumbar fusion surgery, microdiscectomy, hip joint replacement surgery, knee joint replacement surgery, anterior cruciate ligament repair, knee arthroscopy, mastectomy, haemorrhoidectomy, abdominal surgery, radical prostatectomy, thyroid surgery, elective caesarean section, and laparoscopic surgery. Racemic ketamine bolus doses were predominantly 0.25 mg to 1 mg, and infusions 2 to 5 µg/kg/minute; 10 studies used only S-ketamine and one only R-ketamine. Risk of bias was generally low or uncertain, except for study size; most had fewer than 50 participants per treatment arm, resulting in high heterogeneity, as expected, for most analyses. We did not stratify the main analysis by type of surgery or any other factor, such as dose or timing of ketamine administration, and used a non-stratified analysis.Perioperative intravenous ketamine reduced postoperative opioid consumption over 24 hours by 8 mg morphine equivalents (95% CI 6 to 9; 19% from 42 mg consumed by participants given placebo, moderate-quality evidence; 65 studies, 4004 participants). Over 48 hours, opioid consumption was 13 mg lower (95% CI 10 to 15; 19% from 67 mg with placebo, moderate-quality evidence; 37 studies, 2449 participants).Perioperative intravenous ketamine reduced pain at rest at 24 hours by 5/100 mm on a visual analogue scale (95% CI 4 to 7; 19% lower from 26/100 mm with placebo, high-quality evidence; 82 studies, 5004 participants), and at 48 hours by 5/100 mm (95% CI 3 to 7; 22% lower from 23/100 mm, high-quality evidence; 49 studies, 2962 participants). Pain during movement was reduced at 24 hours (6/100 mm, 14% lower from 42/100 mm, moderate-quality evidence; 29 studies, 1806 participants), and 48 hours (6/100 mm, 16% lower from 37 mm, low-quality evidence; 23 studies, 1353 participants).Results for primary outcomes were consistent when analysed by pain at rest or on movement, operation type, and timing of administration, or sensitivity to study size and pain intensity. No analysis by dose was possible. There was no difference when nitrous oxide was used. We downgraded the quality of the evidence once if numbers of participants were large but small-study effects were present, or twice if numbers were small and small-study effects likely but testing not possible.Ketamine increased the time for the first postoperative analgesic request by 54 minutes (95% CI 37 to 71 minutes), from a mean of 39 minutes with placebo (moderate-quality evidence; 31 studies, 1678 participants). Ketamine reduced the area of postoperative hyperalgesia by 7 cm² (95% CI -11.9 to -2.2), compared with placebo (very low-quality evidence; 7 studies 333 participants). We downgraded the quality of evidence because of small-study effects or because the number of participants was below 400.CNS adverse events occurred in 52 studies, while 53 studies reported of absence of CNS adverse events. Overall, 187/3614 (5%) participants receiving ketamine and 122/2924 (4%) receiving control treatment experienced an adverse event (RR 1.2, 95% CI 0.95 to 1.4; high-quality evidence; 105 studies, 6538 participants). Ketamine reduced postoperative nausea and vomiting from 27% with placebo to 23% with ketamine (RR 0.88, 95% CI 0.81 to 0.96; the number needed to treat to prevent one episode of postoperative nausea and vomiting with perioperative intravenous ketamine administration was 24 (95% CI 16 to 54; high-quality evidence; 95 studies, 5965 participants). AUTHORS' CONCLUSIONS Perioperative intravenous ketamine probably reduces postoperative analgesic consumption and pain intensity. Results were consistent in different operation types or timing of ketamine administration, with larger and smaller studies, and by higher and lower pain intensity. CNS adverse events were little different with ketamine or control. Perioperative intravenous ketamine probably reduces postoperative nausea and vomiting by a small extent, of arguable clinical relevance.

Abstract
Objective Inferior and limited analgesic options/techniques during living donor hepatectomy surgery can result in pain and risks of morbidity, opioid-related adverse events (AEs), predisposition to the development of chronic pain and concerns of potential narcotic abuse. Traditional analgesia uses unimodal intravenous opioids that can cause significant side effects. Ketamine provides analgesia and may be opioid sparing, but use in living-donor hepatectomy has not been studied. Methods Following human investigation committee approval and informed written consent, 47 liver donor patients over a 5-year period scheduled for surgery were categorized into one of three groups: 24 patients received no ketamine (Group 1), 9 received only intraoperative ketamine (Group 2) and 14 patients received intraoperative plus postoperative ketamine (Group 3). Subjects had access to opioid patient-controlled analgesia (PCA). Chart reviews (including operating room and intensive care unit) were collected and analysed for morphine consumption, pain-intensity scores, opioid-sparing effects, AEs of analgesics and for evidence of ketamine side effects on donor hepatectomy patients. Results There were no differences in patient demographics. Living donor hepatectomy patients receiving intraoperative ketamine that was continued postoperatively consumed fewer morphine-equivalents and had lower median pain scores than subjects from the other two groups. Ileus occurred in those not receiving ketamine, pruritus was lowest in Group 3, and there was no evidence or reports of ketamine-associated AEs. Conclusion Perioperative ketamine for donor hepatectomy patients could safely provide improved analgesia and be opioid sparing when compared to PCA opioids alone, and there is no evidence of ketamine-related AEs at the dose and delivery methods described here during partial liver donation surgery.

Abstract
STUDY DESIGN A meta-analysis of randomized controlled trials (RCTs). OBJECTIVE The aim of this study was to evaluate the effectiveness of perioperative supplemental ketamine to reduce postoperative opioid analgesic consumption following spine surgery. SUMMARY OF BACKGROUND DATA Although low-dose supplemental ketamine has been known to reduce pain after surgery, there is conflicting evidence regarding whether ketamine can be effective to reduce opioid consumption following spine surgery. METHODS Comprehensive search of PubMed, the Cochrane Central Register of Controlled Trials for prospective RCTs, Web of Science, and Scopus. Patients who received supplemental ketamine were compared with the control group in terms of postoperative morphine equivalent consumption, pain scores, and adverse events. Mean differences (MDs) and 95% confidence intervals (CIs) were used to describe continuous outcomes. Odds ratios (ORs) and 95% CIs were applied to dichotomous outcomes. RESULTS A total of 14 RCTs comprising 649 patients were selected for inclusion into the meta-analysis. Patients who were administered adjunctive ketamine exhibited less cumulative morphine equivalent consumption at 4, 8, 12, and 24 hours following spine surgery (all Ps < 0.05). The ketamine group also reported lower postoperative pain scores at 6, 12, and 24 hours (all Ps < 0.05). None of the adverse events studied attained statistical significance (all Ps > 0.05). CONCLUSION Supplemental perioperative ketamine reduces postoperative opioid consumption up to 24 hours following spine surgery. LEVEL OF EVIDENCE 1.

Abstract
This review includes a summary of contemporary theories of pain processing and advocates a multimodal analgesia approach for providing perioperative care. A summary of various medication classes and anesthetic techniques is provided that highlights evidence emerging from neurosurgical literature. This summary covers opioid management, acetaminophen, nonsteroidal antiinflammatories, ketamine, lidocaine, dexmedetomidine, corticosteroids, gabapentin, and regional anesthesia for neurosurgery. At present, there is not enough investigation into these areas to describe best practices for treating or preventing chronic pain in neurosurgery; but providers can identify a wider range of options available to personalize perioperative care strategies.

Abstract
One of the most fascinating drugs in the anesthesiologist's armament is ketamine, an N-methyl-D-aspartate receptor antagonist with a myriad of uses. The drug is a dissociative anesthetic and has been used more often as an analgesic in numerous hospital units, outpatient pain clinics, and in the prehospital realm. It has been used to treat postoperative pain, chronic pain, complex regional pain syndrome, phantom limb pain, and other neuropathic conditions requiring analgesia. Research has also demonstrated its efficacy as an adjunct in psychotherapy, as a treatment for both depression and posttraumatic stress disorder, as a procedural sedative, and as a treatment for respiratory and neurologic conditions. Ketamine is not without its adverse effects, some of which can be mitigated with certain efforts. Such effects make it necessary for the clinician to use the drug only in situations where it will provide the greatest benefit with the fewest adverse effects. To the best of our knowledge, none of the reviews regarding ketamine have taken a comprehensive look at the drug's uses in all territories of medicine. This review will serve to touch on its chemical data, pharmacokinetics and pharmacodynamics, medical uses, and adverse effects while focusing specifically on the drugs usage in anesthesia and analgesia.

Abstract
Ketamine was introduced into clinical practice in the 1960s and continues to be both clinically useful and scientifically fascinating. With considerably diverse molecular targets and neurophysiological properties, ketamine’s effects on the central nervous system remain incompletely understood. Investigators have leveraged the unique characteristics of ketamine to explore the invariant, fundamental mechanisms of anesthetic action. Emerging evidence indicates that ketamine-mediated anesthesia may occur via disruption of corticocortical information transfer in a frontal-to-parietal (“top down”) distribution. This proposed mechanism of general anesthesia has since been demonstrated with anesthetics in other pharmacological classes as well. Ketamine remains invaluable to the fields of anesthesiology and critical care medicine, in large part due to its ability to maintain cardiorespiratory stability while providing effective sedation and analgesia. Furthermore, there may be an emerging role for ketamine in treatment of refractory depression and Post-Traumatic Stress Disorder. In this article, we review the history of ketamine, its pharmacology, putative mechanisms of action and current clinical applications.

Abstract
OBJECTIVES The objective of this narrative review was to examine the usage of ketamine as a postoperative analgesic agent across a wide variety of surgeries. DESIGN A literature search was performed using the phrases "ketamine" and "postoperative pain." The authors analyzed the studies that involved testing ketamine's effectiveness at controlling postoperative pain. Effectiveness was assessed through various outcomes such as the amount of opiate consumption, visual analog scale (VAS) pain scores, and persistent postoperative pain at long-term follow-up. RESULTS While many different administration protocols were evaluated, delivering ketamine both as a pre- or perioperative bolus and postoperative infusion for up to 48 hours appeared to be the most effective. These effects are dose-dependent. However, a number of studies analyzed showed no benefit in using ketamine versus placebo for controlling postoperative pain. While ketamine is a safe and well-tolerated drug, it does have adverse effects, and there are concerns for possible neurotoxicity and effects on memory. CONCLUSIONS In a number of limited situations, ketamine has shown some efficacy in controlling postoperative pain and decreasing opioid consumption. More randomized controlled trials are necessary to determine the surgical procedures and administrations (i.e., intravenous, epidural) that ketamine is best suited for.

Abstract
Background: Use of opioids for perioperative analgesia is associated with sedation, respiratory depression and postoperative nausea and vomiting. N-methyl-D-aspartate receptor antagonist such as ketamine has both analgesic and antihyperalgesic properties. We studied the effect of intraoperative infusion of low-dose ketamine on postoperative analgesia and its management with opioids. Materials and Methods: A total of 80 patients scheduled for open cholecystectomy under general anesthesia were randomly allocated into two equal groups in a randomized double-blinded way. The general anesthetic technique was standardized in both groups. Group K patients (n = 40) received bolus of ketamine 0.2 mg/kg intravenously followed by an infusion of 0.1 mg/kg/h before skin incision, which was continued up to the end of surgery. Similar volume of saline was infused in Group C (n = 40). The pain score at different intervals and cumulative morphine consumption over 24 h was observed. Secondary outcomes such as hemodynamic parameters, patient satisfaction score and incidences of side effects were also recorded. Results: Intraoperative infusion of low-dose ketamine resulted in effective analgesia in first 6 h of the postoperative period, which was evident from reduced pain scores and reduced opioid requirements (P = 0.001). The incidence of side effects and patient satisfaction were similar in both groups. Conclusion: Intraoperative low-dose ketamine infusion provides good postoperative analgesia while reducing need of opioid analgesics, which must be considered for better management of postoperative analgesia.

Abstract
BACKGROUND Nefopam is a centrally acting analgesic that is used to control pain. The aim of this study was to find an appropriate dose of nefopam that demonstrates an analgesic effect when administered in continuous infusion with fentanyl at the end of laparoscopic cholecystectomy. METHODS Ninety patients scheduled for laparoscopic cholecystectomy were randomly assigned to receive analgesia with fentanyl alone (50 µg, Group 1, n = 30), or with fentanyl in combination with nefopam 20 mg (Group 2, n = 30) or in combination with nefopam 40 mg (Group 3, n = 30) at the end of surgery. Pain and side effects were evaluated at 10 minutes, 30 minutes, 1 hour, 2 hours, 6 hours, and 12 hours after arrival in the post-anesthesia care unit (PACU). RESULTS Pain was statistically significantly lower in Groups 2 and 3 than in Group 1 at 10 minutes, 2 hours, and 6 hours after arrival in the PACU. Nausea was statistically significantly lower in Group 2 than in Groups 1 and 3 at 10 minutes after arrival in the PACU. Shivering was statistically significantly lower in Groups 2 and 3 than in Group 1 at 10 minutes after arrival in the PACU. CONCLUSIONS Nefopam is a drug that can be safely used as an analgesic after surgery, and its side effects can be reduced when fentanyl 50 µg is injected with nefopam 20 mg.
