Postoperative analgesic efficacy of nefopam after anorectal surgery: a retrospective observational study

Objective: To examine the effectiveness of nefopam on postoperative pain control after anorectal surgeries. Methods: We retrospectively reviewed the electronic medical records of patients who underwent anorectal surgeries from January 2019 to March 2022 at two medical centers. The data were divided into nefopam and conventional groups. The primary outcome was the number of patients who requested additional opioids in the 24-h postoperative period. The secondary outcomes were numeric rating pain scores (NRPS) within a 24-h postoperative period and analgesic drugs-related side effects. Results: Eighty-seven patients in the conventional group and 60 in the nefopam group were recruited. The nefopam group reported less additional opioid consumption than the conventional group in all dimensions of analysis, including overall, adjusted to anesthetic techniques and types of surgery. However, these did not reach statistical significance (P = 0.093). Only patients in the nefopam group who underwent hemorrhoidectomy under TIVA or spinal anesthesia significantly required fewer additional opioids (P = 0.016, 60% mean difference). Similarly, the 24-h postoperative morphine consumption was lower in the nefopam group (mean difference = -3.4, 95%CI: 0.72,6.08). Furthermore, significantly lower NRPS were reported in the nefopam group during the 12-18 h postoperative period (P = 0.009). On the other hand, analgesic drugs related side effects were similar in both groups. Conclusions: The administration of nefopam after major anorectal surgery is beneficially evident in reducing postoperative opioid requirements. (AU)

Effectiveness and safety of ultra-low-dose spinal anesthesia versus perineal blocks in hemorroidectomy and anal fistula surgery: a randomized controlled trial

Abstract Background: Ultra-low-dose Spinal Anesthesia (SA) is the practice of employing minimal doses of intrathecal agents so that only the roots that supply a specific area are anesthetized. The aim of this study was to compare the effectiveness and safety of ultra-low-dose spinal anesthesia with that of Perineal Blocks (PB). Methods: A two-arm, parallel, double-blind randomized controlled trial comparing two anesthetic techniques (SA and PB) for hemorrhoidectomy and anal fistula surgery was performed. The primary outcomes were postoperative pain, complementation and/or conversion of anesthesia, and hemodynamic changes. Results: Fifty-nine patients were included in the final analysis. The mean pain values were similar in the first 48 h in both groups (p > 0.05). The individuals allocated to the SA group did not need anesthetic complementation; however, those in the PB group required it considerably (SA group, 0% vs. PB group, 25%; p = 0.005). Hemodynamic changes were more pronounced after PB: during all surgical times, the PB group showed lower MAP values and higher HR values (p < 0.05). Postoperative urinary retention rates were similar between both groups (SA group 0% vs. PB group 3.1%, p = 0.354). Conclusion: SA and PB are similarly effective in pain control during the first 48 h after hemorrhoidec-tomy and anal fistula surgery. Although surgical time was shorter among patients in the PB group, the SA technique may be preferable as it avoids the need for additional anesthesia. Furthermore, the group that received perineal blocks was under sedation with a considerable dose of propofol.

Supra-inguinal fascia iliaca block in older-old patients for hip fractures: a retrospective study

Abstract Background: Pain management in hip fracture patients is of great importance for reducing postoperative morbidity and mortality. Multimodal techniques, including peripheral nerve blocks, are preferred for postoperative analgesia. Older-old hip fracture patients with high ASA scores are highly sensitive to the side effects of NSAIDs and opioids. Our aim was to investigate the effectiveness of the recently popularized Supra-Inguinal Fascia Iliaca Block (SIFIB) in this population. Methods: Forty-one ASA III-IV patients who underwent SIFIB + PCA (G-SIFIB) or PCA alone (Group Control: GC) after general anesthesia were evaluated retrospectively. In addition to 24-hour opioid consumption, Visual Analog Scale (VAS) scores, opioid-related side effects, block-related complications, and length of hospital stay were compared. Results: Twenty-two patients in G-SIFIB and 19 patients in GC were evaluated. The postoperative 24-hour opioid consumption was lower in G-SIFIB than in GC (p < 0.001). There was a statistically significant reduction in VAS scores at the postoperative 1st, 3rd, and 6th hours at rest (p < 0.001) and during movement (p < 0.001 for the 1st and 3rd hours, and p = 0.02 for the 6th hour) in G-SIFIB compared to GC. There was no difference in pain scores at the 12th and 24th hours postoperatively. While there was no difference between the groups in terms of other side effects, respiratory depression was significantly higher in GC than in G-SIFIB (p = 0.01). Conclusion: The SIFIB technique has a significant opioid-sparing effect and thus reduces opioid-related side effects in the first 24 hours after hip fracture surgery in older-old patients.

Pericapsular Nerve Group (PENG) block versus fascia iliaca compartment (FI) block for hip surgery: a systematic review and meta-analysis of randomized controlled trials

Abstract Background: This study compares Fascia Iliaca compartment (FI) block and Pericapsular Nerve Group (PENG) block for hip surgery. Methods: Pubmed, Embase and Cochrane were systematically searched in April 2022. Inclusion criteria were: Randomized Controlled Trials (RCTs); comparing PENG block versus FI block for hip surgery; patients over 18 years of age; and reporting outcomes immediately postoperative. We excluded studies with overlapped populations and without a head-to-head comparison of the PENG block vs. FI block. Mean-Difference (MD) with 95% Confidence Intervals (CI) were pooled. Trial Sequential Analyses (TSA) were performed to assess inconsistency. Quality assessment and risk of bias were performed according to Cochrane recommendations. Results: Eight RCTs comprising 384 patients were included, of whom 196 (51%) underwent PENG block. After hip surgery, PENG block reduced static pain score at 12h post-surgery (MD = 0.61 mm; 95% CI 1.12 to -0.09; p = 0.02) and cumulative postoperative oral morphine consumption in the first 24h (MD = -6.93 mg; 95% CI -13.60 to -0.25; p = 0.04) compared with the FI group. However, no differences were found between the two techniques regarding dynamic and static pain scores at 6 h or 24 h post-surgery, or in the time to the first analgesic rescue after surgery. Conclusion: The findings suggest that PENG block reduced opioid consumption in the first 24 h after surgery and reduced pain scores at rest at 12 h post-surgery. Further research is needed to fully understand the effects of the PENG block and its potential benefits compared to FI block.

Perineural low dexamethasone dose as adjuvant in supraclavicular brachial plexus block for arteriovenous fistula creation in end stage renal disease: a randomized controlled trial

Abstract Background and aims: Dexamethasone as adjunct to local anesthetic solution improves the quality of brachial plexus block (BPB). However, evidence for its efficacy at low doses (< 4 mg) is lacking. This study was designed to evaluate the duration of analgesia attained with low dose dexamethasone as adjuvant to local anesthetic for creation of arteriovenous fistula (AVF) under BPB. Methods: Sixty-six patients scheduled for AVF creation were randomly allocated to receive either saline (control) or 2 mg dexamethasone, together with 0.5% ropivacaine and 0.2% lignocaine. The primary outcome was duration of analgesia, defined as time from performing the block to the first analgesic request. The secondary outcomes were time from injection to complete sensory block, time from injection to complete motor block, duration of motor block, postoperative analgesic consumption, and fistula patency at three months. Results: All the blocks were effective. In the group that received dexamethasone, the time to first analgesic request was significantly delayed (432 ± 43.8 minutes vs. 386.4 ± 40.2 minutes; p < 0.01). The onset of sensory and motor blockade occurred faster in dexamethasone group and overall analgesic consumption was also reduced. However, dexamethasone addition did not prolong the duration of motor block. There was no statistically significant difference in the patency of fistulas between the two groups at three months. (p = 0.34). Conclusion: Addition of low-dose perineural dexamethasone to local anesthetic solution significantly prolonged the duration of analgesia. Further trials are warranted to compare the adverse effects between dexamethasone doses of 4 mg and lower.

Quadratus Lumborum block as primary anesthetic technique for colostomy procedure: a case report

Abstract An elderly patient was admitted to the hospital due to an enterovesical fistula and a terminal colostomy was proposed. The patient had a high anesthetic risk and thus a quadratus lumborum block was chosen as the sole anesthetic technique. This block has been described to provide both somatic and visceral analgesia to the abdomen. In fact, it yielded good anesthetic conditions to perform the procedure and allowed the patient to be hemodynamically stable and comfortable throughout the case. The postoperative period was uneventful.

Actualización en analgesia preventiva y analgesia multimodal / Update on preventive analgesia and multimodal analgesia

Una deficiente calidad del manejo del dolor post operatorio agudo genera aumento en la morbilidad perioperatoria, disminuye la calidad de vida del paciente, aumenta los reingresos hospitalarios y, finalmente, los costes en salud. La analgesia preventiva y multimodal son dos estrategias que han sido implementadas para tratar de optimizar el manejo del dolor. Si bien en la primera, la evidencia es favorable a su empleo, aún no existe un total consenso en esto. A su vez, la analgesia multimodal, al emplear diferentes fármacos y/o técnicas, ha logrado evidenciar de mejor manera su utilidad y los beneficios al implementarla como terapia. En este artículo, revisamos la evidencia que certifica y avala el uso de éstas. Finalmente, a nuestro parecer, lo más importante en el quehacer del clínico, es lograr individualizar la estrategia que usaremos en el manejo del dolor postoperatorio, adaptándonos a las necesidades y el contexto propio de cada uno de nuestros pacientes.

A poor quality of acute postoperative pain management generates an increase in perioperative morbidity, decreases the quality of life of the patient, increases hospital readmissions and finally, increases health costs. Preventive and multimodal analgesia are two strategies that are implemented to try to optimize pain management. Although in the first, the evidence is favorable to its use, there is still no total consensus. At the same time, multimodal analgesia, by using different drugs and/or techniques, has demonstrated, in a better way, its usefulness and benefits when implemented as a therapy. In this article, we review the evidence that certifies and supports the use of these techniques. Finally, in our opinion, the most important thing in the clinician's task is to be able to individualize the strategy that we will use in postoperative pain management, adapting to the needs and context of each one of our patients.

Ultrasound-guided continuous costoclavicular block through retrograde stimulating catheter technique for postoperative analgesia in shoulder surgery: a case series

Abstract In five patient undergoing surgery for proximal humerus fracture we investigated into postoperative analgesia provided by continuous costoclavicular block using continuous stimulating catheter. The postoperative pain scores were less than 4 in all patients except in two patients who required intravenous tramadol 50 mg as a rescue analgesic. The radiocontrast dye study executed in two patients revealed contiguous contrast spread through the brachial plexus sheath with the catheter tip in the interscalene space. We propose that a continuous costoclavicular block with a retrograde stimulating catheter is a feasible alternative regional anesthesia technique for postoperative analgesia in shoulder surgery.

Evaluación del dolor crónico postoperatorio en hernioplastia TAPP versus Lichtenstein por Residentes / Evaluation of chronic postoperative pain in hernioplasty Tapp versus Lichtenstein by residents

La incidencia de la hernia inguinal a lo largo de la vida es variable, pero con una mayor prevalencia en los hombres. Hoy en día no existe una técnica superior en términos de reducir el dolor postoperatorio crónico, que es la mayor morbilidad que afecta a los pacientes. Es por eso que realizamos un breve análisis comparativo, donde evaluamos la incidencia de dolor crónico entre el ensayo convencional versus laparoscópico de la patología de la hernia

The incidence of inguinal hernia throughout life is variable, but with a higher prevalence in males. Today there is no superior technique in terms of reducing chronic postoperative pain, which is the greatest morbidity that afflicts patients. That is why we carried out a brief comparative analysis, where we evaluated the incidence of chronic pain between conventional versus laparoscopic rehearsal of hernia pathology

Safety and effectiveness of adding fentanyl or sufentanil to spinal anesthesia: systematic review and meta-analysis of randomized controlled trials

Abstract Introduction Spinal infusions of either fentanyl or sufentanil have been reported in international reports, articles, and scientific events worldwide. This study aimed to determine whether intrathecal fentanyl or sufentanil offers safety in mortality and perioperative adverse events. Methods MEDLINE (via PubMed), EMBASE, CENTRAL (Cochrane library databases), gray literature, hand-searching, and clinicaltrials.gov were systematically searched. Randomized controlled trials with no language, data, or status restrictions were included, comparing the effectiveness and safety of adding spinal lipophilic opioid to local anesthetics (LAs). Data were pooled using the random-effects models or fixed-effect models based on heterogeneity. Results The initial search retrieved 4469 records; 3241 records were eligible, and 3152 articles were excluded after reading titles and abstracts, with a high agreement rate (98.6%). After reading the full texts, 76 articles remained. Spinal fentanyl and sufentanil significantly reduced postoperative pain and opioid consumption, increased analgesia and pruritus. Fentanyl, but not sufentanil, significantly reduced both postoperative nausea and vomiting, and postoperative shivering; compared to LAs alone. The analyzed studies did not report any case of in-hospital mortality related to spinal lipophilic opioids. The rate of respiratory depression was 0.7% and 0.8% when spinal fentanyl or sufentanil was added and when it was not, respectively. Episodes of respiratory depression were rare, uneventful, occurred intraoperatively, and were easily manageable. Conclusion There is moderate to high quality certainty that there is evidence regarding the safety and effectiveness of adding lipophilic opioids to LAs in spinal anesthesia.

Effect of magnesium sulfate with ketamine infusions on intraoperative and postoperative analgesia in cancer breast surgeries: a randomized double-blind trial

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 mg.kg-1 bolus then 0.12 mg.kg-1.h-1 infusion for the first 24 hours postoperatively. Group KM: received ketamine 0.5 mg.kg-1 and Mg sulfate 50 mg.kg-1, then ketamine 0.12 mg.kg-1.h-1 and Mg sulfate 8 mg.kg-1.h-1 infusions for the first 24 hours postoperative. The primary outcome was the morphine consumption in the first 24 hours 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 ± 5.11 mg) than Group K (19.43 ± 6.8 mg). 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.

Efectividad del uso transoperatorio de solución electrolizada de superoxidación para la prevención de infecciones postoperatorias en cirugía de terceros molares / Effectiveness of the trans-operative use of electrolyzed superoxidation solution for the prevention of post-operative infections in third molar surgery

La cirugía de terceros molares es uno de los procedimientos más realizados dentro de la práctica odontológica, generalmente conlleva la prescripción de fármacos, incluidos antibióticos indicados para prevenir la aparición de procesos infecciosos. La resistencia antimicrobiana es considerada como un problema de salud pública a nivel mundial, por lo que el uso de antibióticos debe ser cauteloso. La solución electrolizada de súperoxidación ha demostrado tener efectos bactericidas, virucidas y ha sido utilizada para la prevención y el tratamiento de procesos infecciosos. El objetivo del presente estudio fue demostrar la efectividad de dicha solución en la prevención de infecciones posteriores a la cirugía de terceros molares. Se realizó un estudio aleatorizado, ciego, prospectivo en 20 pacientes utilizando un diseño split mouth, en donde cada paciente fue sujeto control y experimental, en el grupo control se irrigó durante el procedimiento con solución de súperoxidación y no se prescribió antibiótico posterior, mientras que en el grupo control se irrigó con solución fisiológica y se prescribió antibiótico posterior. Se realizaron 40 cirugías en 20 pacientes utilizando en cada paciente ambas terapéuticas. Se analizó el dolor postoperatorio, inflamación y presencia de infección. El dolor y la inflamación fueron ligeramente superiores en el grupo experimental al tercer día; sin embargo, al séptimo día los resultados fueron similares. No se presentó ningún caso de infección postoperatoria. El uso de solución de súperoxidación transoperatoria puede ser una herramienta muy útil en la prevención de infecciones postoperatorias posterior a cirugía de terceros molares en pacientes sanos en cirugías con dificultad leve a moderada (AU)

Third molar surgery is one of the most performed procedures in dental practice, generally involving the prescription of drugs including antibiotics indicated to prevent the onset of infectious processes. Antimicrobial resistance is considered a public health problem worldwide, so the use of antibiotics should be cautious. The electrolyzed super oxidation solution has been shown to have bactericidal and virucidal effects and has been used for the prevention and treatment of infectious processes. The objective of the present study was to demonstrate the effectiveness of said solution in the prevention of infections after third molar surgery. A randomized, blind, prospective study was conducted in 20 patients using a split mouth design where each patient was a control and experimental subject, in the control group they were irrigated during the procedure with super oxidation solution and no subsequent antibiotic was prescribed. while the control group was irrigated with physiological solution and a subsequent antibiotic was prescribed. Forty surgeries were performed on 20 patients using both therapies in each patient. Postoperative pain, inflammation and presence of infection were analyzed. Pain and inflammation were slightly higher in the experimental group on third day, however on seventh day the results were similar. There were no cases of postoperative infection. The use of trans operative super oxidation solution can be a very useful tool in the prevention of postoperative infections after third molar surgery in healthy patients undergoing surgeries with mild to moderate difficulty.(AU)

Bilateral versus unilateral erector spinae plane block for postoperative analgesia in laparoscopic cholecystectomy: a randomized controlled study

Abstract Introduction Laparoscopic cholecystectomy (LC) is the common surgical intervention for benign biliary diseases. Postoperative pain after LC remains as an important problem, with two components: somatic and visceral. Trocar entry incisions lead to somatic pain, while peritoneal distension with diaphragm irritation leads to visceral pain. Following its description by Forero et al., the erector spinae plane (ESP) block acquired considerable popularity among clinicians. This led to the use of ESP block for postoperative pain management for various operations. Materials and methods This study was conducted between January and June 2019. Patients aged between 18 and 65 years with an American Society of Anesthesiologists (ASA) physical status I-II, scheduled for elective laparoscopic cholecystectomy were included in the study. All the patients received bilateral or unilateral ESP block at the T8 level preoperatively according to their groups. Results There was no significant difference between the groups in terms NRS scores either at rest or while coughing at any time interval except for postoperative 6th hour (p = 0.023). Morphine consumption was similar between the groups but was significantly lower in group B at 12 and 24 hours (p = 0.044 and p = 0.022, respectively). Twelve patients in group A and three patients in group B had shoulder pain and this difference was statistically significant (p = 0.011). Discussion In conclusion, bilateral ESP block provided more effective analgesia than unilateral ESP block in patients undergoing elective LC. Bilateral ESP block reduced the amount of opioid consumption and the incidence of postoperative shoulder pain.

Effect of preoperative anxiety level on postoperative pain, analgesic consumption in patients undergoing laparoscopic sleeve gastrectomy: an observational cohort study

Abstract Backgraund: This prospective observational cohort study aimed to investigate the relationship between preoperative anxiety levels and postoperative pain and analgesic requirement in patients undergoing laparoscopic sleeve gastrectomy. Methods: Forty two female patients with body mass index ≥ 35, who underwent laparoscopic sleeve gastrectomy for treatment of obesity were included in the study. Spielberger's state and trait anxiety scales were used in this study. Demographic data of the patients, anesthetic and analgesic drugs during the surgery, pain levels measured with verbal analog scale at the postoperative 1st, 4th, 12th, and 24th hour, sedation levels measured with the Ramsay sedation scale, and the amount of analgesic consumed were recorded. Anesthesiologist, surgeon, and patient were not informed of the anxiety level results. The relationship between preoperative anxiety and postoperative pain and analgesic consumption was evaluated by Spearman's correlation analysis. Stepwise multiple linear regression analysis was applied. Normal Distribution control was performed by applying the Shapiro-Wilk test to residual values obtained from the final model. Results: There was no relationship between trait anxiety level and postoperative pain and analgesic consumption. A correlation was found between state anxiety level and pain level up to 24 hours and analgesic consumption (p < 0.05). According to the obtained model it had been observed that the university graduates consumed more analgesic compared to other education level groups. Conclusion: In this study, a relationship was found between preoperative state anxiety level and 24-hour pain scores and analgesic consumption in patients who underwent laparoscopic sleeve gastrectomy under general anesthesia.

Regional analgesia and surgical site infections after colorectal surgery: a retrospective cohort analysis

Abstract Background The effect of regional analgesia on perioperative infectious complications remains unknown. We therefore tested the hypothesis that a composite of serious infections after colorectal surgery is less common in patients with regional analgesia than in those given Intravenous Patient-Controlled Analgesia (IV-PCA) with opiates. Methods Patients undergoing elective colorectal surgery lasting one hour or more under general anesthesia at the Cleveland Clinic Main Campus between 2009 and 2015 were included in this retrospective analysis. Exposures were defined as regional postoperative analgesia with epidurals or Transversus Abdominis Plane blocks (TAP); or IV-PCA with opiates only. The outcome was defined as a composite of in-hospital serious infections, including intraabdominal abscess, pelvic abscess, deep or organ-space Surgical Site Infection (SSI), clostridium difficile, pneumonia, or sepsis. Logistic regression model adjusted for the imbalanced potential confounding factors among the subset of matched surgeries was used to report the odds ratios along with 95% confidence limits. The significance criterion was p < 0.05. Results A total of 7811 patients met inclusion and exclusion criteria of which we successfully matched 681 regional anesthesia patients to 2862 IV-PCA only patients based on propensity scores derived from potential confounding factors. There were 82 (12%) in-hospital postoperative serious infections in the regional analgesia group vs. 285 (10%) in IV-PCA patients. Regional analgesia was not significantly associated with serious infection (odds ratio: 1.14; 95% Confidence Interval 0.87‒1.49; p-value = 0.339) after adjusting for surgical duration and volume of intraoperative crystalloids. Conclusion Regional analgesia should not be selected as postoperative analgesic technique to reduce infections.

Inkk Trial - Intraoperative ketamine for perioperative pain management following total knee endoprosthetic replacement in oncology: a double-blinded randomized trial

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 hours post-surgery. Our secondary objectives were to compare the opioid requirement at the end of 72 hours, 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 mg.kg-1 before the incision followed by 10 µg.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 hours. The TUG tests and range of motion were assessed by the physiotherapists until 72 hours. 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.
