Abstract Background The effect of volatile anesthetics on emergence agitation in adults remains unclear. We compared the degree of emergence agitation between desflurane and sevoflurane anesthesia in adults undergoing thyroid surgery. Findings One hundred and sixteen patients with American Society of Anesthesiologists status 1 or 2 were randomized into two groups: the desflurane group (group D) and the sevoflurane group (group S). After induction of anesthesia with fentanyl (1–2 μg/kg) and propofol (1.5–2.5 mg/kg), tracheal intubation was facilitated with suxamethonium (0.5–1.0 mg/kg). In group D, anesthesia was maintained with desflurane in 66% nitrous oxide and 33% oxygen supplemented with fentanyl when necessary; in group S, sevoflurane was used instead of desflurane. After the end of the surgery, emergence agitation was evaluated with a modified pediatric anesthesia emergence delirium scale (ranging from 0 to 16, with higher scores indicating more severe emergence agitation) before extubation. Time to extubation from the end of the surgery, postoperative pain (evaluated by a numerical rating scale [NRS]), and postoperative nausea and vomiting (PONV) after surgery were examined. The degree of emergence agitation was more severe in group D than in group S (median [interquartile range]: 5 [4–7] vs 4 [2–6], p = 0.008). Time to extubation, NRS scores, and PONV rates were similar between the two groups. Conclusions Desflurane anesthesia worsened emergence agitation as compared with sevoflurane in adult patients undergoing thyroid surgery, but did not affect time to extubation, postoperative pain, or PONV.

Background: Craniotomy causes acute and chronic pain. Uncontrolled postoperative pain may lead to adverse events. Perioperative scalp nerves block is not only effective in reducing intraoperative hemodynamic response, but it also reduces postoperative pain and postoperative analgesia requirement. Objective: To compare the benefits of adding dexmedetomidine to levobupivacaine in scalp nerves block before craniotomy for the duration of analgesia in supratentorial craniotomy. Materials and Methods: After approval by the Committee for Research, 50 supratentorial craniotomy patients were randomized into two groups. The control group received 30 mL scalp nerves block with 0.25% levobupivacaine with adrenaline 1:200,000, whereas the study group received 30 mL scalp nerves block with 0.25% levobupivacaine with adrenaline 1:200,000 plus dexmedetomidine 1 mcg/kg. The primary outcome was the time to first analgesic requirement postoperatively. The secondary outcomes included intraoperative fentanyl consumption, verbal numerical rating scale, tramadol consumption, and complications during the first 24 hours postoperatively. Results: Patients in the study group had significantly increase time to the first analgesic requirement in postoperative period and reduced intraoperative fentanyl consumption. The median time to first analgesic requirement was 555 (360 to 1,035) minutes in the study group versus 405 (300 to 520) minutes in the control group (p=0.023). Intraoperative fentanyl consumption 125 (75 to 175) mcg in the study group was significantly lower than 200 (150 to 250) mcg in the control group (p=0.02). The verbal numerical rating scale at 1, 4, 8, 12 and 24 hours postoperatively, tramadol consumption, and complications during the first 24 hours postoperatively were not statistically significant different. Conclusion: Preoperative scalp nerves block with 0.25% levobupivacaine with adrenaline (1:200,000) with dexmedetomidine 1 mcg/kg significantly increased the time to first analgesic requirement and reduced intraoperative fentanyl consumption compared to 0.25% levobupivacaine with adrenaline (1:200,000) without perioperative complications.

Abstract Purpose Even though anastomotic leakage after colorectal surgery is a major clinical problem in need of a timely diagnosis, early indicators of leakage have been insufficiently studied. We therefore conducted a population-based observational study to determine whether the patient’s early postoperative pain is an independent marker of anastomotic leakage. Methods By combining the Swedish Colorectal Cancer Registry and the Swedish Perioperative Registry, we retrieved prospectively collected data on 3084 patients who underwent anastomotic colorectal surgery for cancer in 2014–2017. Postoperative pain, measured with the numerical rating scale (NRS), was considered exposure, while anastomotic leakage and reoperation due to leakage were outcomes. We performed logistic regression to evaluate associations, estimating odds ratios (ORs) and 95% confidence intervals (CIs), while multiple imputation was used to handle missing data. Results In total, 189 patients suffered from anastomotic leakage, of whom 121 patients also needed a reoperation due to leakage. Moderate or severe postoperative pain (NRS 4–10) was associated with an increased risk of anastomotic leakage (OR 1.69, 95% CI 1.21–2.38), as well as reoperation (OR 2.17, 95% CI 1.41–3.32). Severe pain (NRS 8–10) was more strongly related to leakage (OR 2.38, 95% CI 1.44–3.93). These associations were confirmed in multivariable analyses and when reoperation due to leakage was used as an outcome. Conclusion In this population-based retrospective study on prospectively collected data, increased pain in the post-anaesthesia care unit is an independent marker of anastomotic leakage, possibly indicating a need for further diagnostic measures.

Abstract Background Bleeding after thyroidectomy occurs due to violent coughing during emergence. Dexmedetomidine is helpful for the smooth emergence and suppression of cough. The purpose of the present study was to compare the effects of dexmedetomidine on postoperative bleeding after thyroidectomy. Methods Randomized, double-blind, controlled trials were conducted in female patients (ASA I–II, aged 20 to 60 years). The patients were randomly allocated into two groups. Approximately 15 min before the end of the surgery, dexmedetomidine was administered (0.6 µg/kg/h) without a loading dose in group D (n = 69), and normal saline was administered in group S (n = 70) at the same infusion rate. Hemodynamic data, coughing reflex, extubation time, Ramsay sedation scale (RSS), and recovery time were assessed during the administration of the study drugs and recovery from anesthesia. The amount of postoperative hemorrhage was measured for 3 days. Results Data from a total of 139 patients were analyzed. The incidence of severe cough was significantly lower in group D than in group S (4.3 % vs. 11.5 %, P = 0.022). The emergence agitation in the postanesthetic care unit was significantly lower in group D than in group S (P = 0.01). Postoperative bleeding was significantly lower in group D than in group S until the second postoperative day (P = 0.015). Conclusions Dexmedetomidine can be helpful in decreasing bleeding after thyroidectomy by reducing coughing and emergence agitation. Trial registration This study was registered at http://clinicaltrials.gov (registration number NCT02412150, 09/04/2015).

Abstract Objective: To explore the goal of pain control in patients after arthroscopic surgery.Design: Investigation. Postoperative pain, pain control satisfaction and the effect of pain on daily activities were investigated and evaluated.Setting: Department of Sports Medicine,Peking University 3rd Hospital,Beijing, P.R.ChinaSubjects: 514 patients selected by convenience sampling from patients hospitalized in a level A hospital in Beijing from 2020.06-2020.11. The patient inclusion criteria were an age of at least 18 years, no history of diagnosis of mental illness, the ability to clearly express his or her pain and an agreement to voluntarily cooperate with the investigators. The exclusion criteria were patients who were unable to complete follow-up.Methods: Postoperative pain, pain control satisfaction and the effect of pain on daily activities were investigated and evaluated by administering a homemade questionnaire to 514 patients selected by convenience sampling from patients hospitalized in a level A hospital in Beijing from 2020.06-2020.11. Pain was assessed using a digital pain numerical rating scale (NRS) (0-10), and a digital score ranging from 0 to 10 was used for satisfaction with pain control and the impact of pain on aspects of daily living.Results: The pain level was most severe in patients 6-24 hours after arthroscopic surgery, during which pain control satisfaction was at its worst. The pain score was significantly related to the effects of pain on aspects of daily life, and the degree of these effects changed significantly for pain scores greater than 2 points.Conclusion: Pain control 6 to 24 hours after surgery is not satisfactory. It is recommended that a pain score of 2 points is used as the goal for pain control after arthroscopic surgery to guide both doctors and patients to effectively control postoperative pain.

OBJECTIVES : To study the role of dexmedetomidine on emergence agitation and its effect on extubation in paediatric adenotonsillectomy. Our study involves the assessment of postoperative pain by Objective Pain Scale and need for rescue analgesia and other untoward events in PACU. The study also included the comparision of post operative recovery time by Modified Aldrete Recovery Score using dexmedetomidine and normal saline in adenotonsillectomy for pediatric patients. METHODS : After induction of general anesthesia patient was put on controlled ventilation and maintained on sevoflurane 1.5-2% with 66% O2 and 33% N2O. At the end of surgery patients received either dexmedetomidine or normal saline over a period of 5 minutes, sevoflurane and nitrous oxide were discontinued, and residual muscle relaxation was reversed. Tracheal extubation time (time from anesthetic gas discontinue to tracheal extubation) and emergence time (time from anesthetic gas discontinue to eye opening on command) were recorded. Incidence of untoward airway events after extubation were also noted. The subject’s postoperative behaviour was assessed using Pediatric Anesthesia Emergence Delirium (PAED). In PACU, the intensity of pain was assessed by using an observational pain score (OPS). Any untoward events were noted and patient was shifted as per modified PACU score. RESULTS: In this randomized comparative study, single dose of dexmedetomidine (0.5mcg/kg) was found to be associated with a statistically significant decrease in the incidence of emergence agitation along with smooth extubation in pediatric patients undergoing adenotonsillectomy with sevoflurane anesthesia. In addition, lower incidence of post-operative nausea and vomiting, lower pain score and shorter duration of stay in post-anesthesia care unit were observed. Although it was seen that the extubation was prolonged in the dexmedetomidine group in comparison to the placebo. CONCLUSION: Dexmedetomidine reduces emergence agitation and provides smooth extubation in pediatric adenotonsillectomy patients on sevoflurane anesthesia.

This equivalence, randomized, clinical trial aimed to compare the postoperative pain of root canal therapy (RCT) with pulpotomy with mineral trioxide aggregate (PMTA) or calcium-enriched mixture (PCEM) in permanent mature teeth. In seven academic centers, 550 cariously exposed pulps were included and randomly allocated into PMTA (n = 188), PCEM (n = 194), or RCT (n = 168) arms. Preoperative “Pain Intensity” (PI) on Numerical Rating Scale and postoperative PIs until day 7 were recorded. Patients’ demographic and pre-/intra-/postoperative factors/conditions were recorded/analysed. The arms were homogeneous in terms of demographics. The mean preoperative PIs were similar (P=0.998), the mean sum PIs recorded during 10 postoperative intervals were comparable (P=0.939), and the trend/changes in pain relief were parallel (P=0.821) in all study arms. The incidences of preoperative moderate-severe pain in RCT, PMTA, and PCEM arms were 56.5%, 55.7%, and 56.7%, which after 24 hours considerably decreased to 13.1%, 10.6%, and 12.9%, respectively (P=0.578). The time span of endodontic procedures was statistically different; RCT = 69.73, PMTA = 35.37, and PCEM = 33.62 minutes (P<0.001). Patients with greater preoperative pain, symptomatic apical periodontitis, or presence of PDL widening suffered more pain (P=0.002, 0.035, and 0.023, resp.); however, other pre-/intra-/postoperative factors/conditions were comparable. Pulpotomy with MTA/CEM and RCT demonstrate comparable and effective postoperative pain relief.

BackgroundThe purpose of this study is to evaluate the efficacy and safety of electroacupuncture (EA) for postoperative pain after laparoscopic appendectomy compared with sham electroacupuncture (SEA) and no acupuncture treatment.Methods and analysisThis study is a protocol for a three-arm, randomised, patient-assessor-blinded (to the type of acupuncture treatment), controlled, parallel trial. 138 participants diagnosed with appendicitis and scheduled for laparoscopic appendectomy will be randomly assigned to the EA group (n=46), SEA group (n=46) or control group (n=46). The EA group will receive acupuncture treatment at both regional and distal acupuncture points with electrostimulation. The SEA group will receive sham acupuncture treatment with mock electrostimulation. Both EA and SEA groups will receive a total of four treatments 1 hour preoperative, 1 hour postoperative and during the morning and afternoon the day after surgery with the same routine postoperative pain control. The control group will receive only routine postoperative pain control. The primary outcome is the 11-point Pain Intensity Numerical Rating Scale (PI-NRS) at 24 hours after surgery. The secondary outcomes are the PI-NRS, analgesic consumption, opioid-related side effects, time to first passing flatus, quality of life and adverse events evaluated 6, 12, 24 and 36 hours and 7 days after surgery.Ethics and disseminationThe study was planned in accordance with the Helsinki Declaration and the Korean Good Clinical Practice Guidelines to protect the participants and was approved by the institutional review board (IRB) of Kyung Hee University Medical Center (KMC IRB-1427–02). The results will be disseminated in peer-reviewed journals and presented at international conferences.Trial registration numberClinical Research Information Service (KCT0001328).

Background. Pain is the most common complication in the postoperative period. If adequate treatment is not taken, it can transform to chronic pain. Postoperative pain brings a lot of social, psychological and financial problems for patients and their families. Materials and methods. This prospective study included 30 patients after laparatomic liver resection operation. Patients were randomly assign­ ed to Infiltrated or Control groups. An infiltration of 40 ml levobupivacaine 0.25% solution to the operation cut edges was performed to the Infiltrated group. The pain was evaluated using the numerical rating scale after 2, 5, 12, 24, 48 hours and 1 month after the operation. Our aim was to determine the effect of local anesthesia in the operation wound. The total usage of morphine and any side effects were registered. Results. A statistically significant reduction in pain was observed in the Infiltrated group in all evaluation periods. Opioids usage was higher in the Control group almost by 4 times and adverse effects were 9 to 1 compared to the Infiltrated group. Conclusions. Surgical wound infiltration with local anesthetic for postoperative pain management after liver resection operations has a positive effect on postoperative pain reduction and leads to lesser usage of opioid analgetics. As a result, there is a less chance of opioids induced adverse effects.

Abstract Background Patient-controlled analgesia (PCA) is a common method for postoperative pain therapy, but it is characterized by large variation of plasma concentrations. PCA with target-controlled infusion (TCI-PCA) may be an alternative. In a previous analysis, the authors developed a pharmacokinetic model for hydromorphone. In this secondary analysis, the authors investigated the feasibility and efficacy of TCI-PCA for postoperative pain therapy with hydromorphone. Methods Fifty adult patients undergoing cardiac surgery were enrolled in this study. Postoperatively, hydromorphone was applied intravenously during three sequential periods: (1) as TCI with plasma target concentrations of 1 to 2 ng/ml until extubation; (2) as TCI-PCA with plasma target concentrations between 0.8 and 10 ng/ml during the following 6 to 8 h; and (3) thereafter as PCA with a bolus dose of 0.2 mg until the next morning. During TCI-PCA, pain was regularly assessed using the 11-point numerical rating scale (NRS). A pharmacokinetic/pharmacodynamic model was developed using ordinal logistic regression based on measured plasma concentrations. Results Data of 43 patients aged 40 to 81 yr were analyzed. The hydromorphone dose during TCI-PCA was 0.26 mg/h (0.07 to 0.93 mg/h). The maximum plasma target concentration during TCI-PCA was 2.3 ng/ml (0.9 to 7.0 ng/ml). The NRS score under deep inspiration was less than 5 in 83% of the ratings. Nausea was present in 30%, vomiting in 9%, and respiratory insufficiency in 5% of the patients. The EC50 of hydromorphone for NRS of 4 or less was 4.1 ng/ml (0.6 to 12.8 ng/ml). Conclusion TCI-PCA with hydromorphone offered satisfactory postoperative pain therapy with moderate side effects.
