Validity and reliability of the Korean version of the Quality of Recovery-40 questionnaire

Opioid-Free Using Ketamine versus Opioid-Sparing Anesthesia during the Intraoperative Period in Video-Assisted Thoracoscopic Surgery: A Randomized Controlled Trial

Opioids effectively manage perioperative pain but have numerous adverse effects. Opioid-free anesthesia (OFA) eliminates intraoperative opioid use; however, evidence for its use in video-assisted thoracoscopic surgery (VATS) is limited. This study assessed the effect of OFA using ketamine in VATS patients compared to opioid-sparing anesthesia (OSA). A total of 91 patients undergoing VATS lobectomy or segmentectomy were randomized to either the OFA group (ketamine) or the OSA group (remifentanil). The primary outcome was the quality of recovery (QoR) on postoperative day (POD) 1, measured with the QoR-40 questionnaire. Secondary outcomes included postoperative pain scores and adverse events. Both groups had comparable baseline and surgical characteristics. On POD 1, the QoR-40 score was higher in the OFA group than in the OSA group (164.3 ± 10.8 vs. 158.7 ± 10.6; mean difference: 5.6, 95% CI: 1.1, 10.0; p = 0.015), though this did not meet the pre-specified minimal clinically important difference of 6.3. The visual analog scale score was lower in the OFA group as compared to the OSA group at 0-1 h (4.2 ± 2.3 vs. 6.2 ± 2.1; p < 0.001) and 1-4 h after surgery (3.4 ± 1.8 vs. 4.6 ± 1.9; p = 0.003). The OFA group had a lower incidence of PONV (2 [4.4%] vs. 9 [19.6%]; p = 0.049) and postoperative shivering (4 [8.9%] vs. 13 [28.3%]; p = 0.030) than the OSA group at 0-1 h after surgery. Using OFA with ketamine proved feasible, as indicated by the stable intraoperative hemodynamics and absence of intraoperative awareness. Patients undergoing VATS with OFA using ketamine showed a statistically significant, but clinically insignificant, QoR improvement compared to those receiving OSA with remifentanil.

Application of the quality of recovery-40 questionnaire to evaluate the effectiveness of enhanced recovery after surgery protocols in gastric cancer

Patient reported outcomes is currently considered to be an important supplement to evaluate the effectiveness of enhanced recovery after surgery (ERAS) clinical practice. The Quality of Recovery-40 Questionnaire (QoR-40) is one of the most frequently used and validation tool to assess the subjective feelings of quality of life after surgery. The present study aimed to use the QoR-40 to evaluate the effectiveness of ERAS protocols in gastric cancer from the perspective of patient-reported quality of recovery. The study was designed as a prospective, non-randomized clinical trial, conducted in a single center. Patients in our hospital who were scheduled to undergo radical surgery for gastric cancer were divided into ERAS group and control group (Contr group). The QoR-40 were administered one day before surgery (Baseline) and on postoperative day 1, 3, 6, and 30. The difference in QoR-40 scores between the ERAS and Contr groups was compared by repeated-measures ANOVA. A total of 200 patients completed the study, including 100 patients in the ERAS group and 100 patients in the Contr group. The Baseline time point QoR-40 scores of the ERAS and Contr groups were 179.68 ± 14.46 and 180.12 ± 17.12, respectively, and no significant difference was noted between the two groups (p = 0.845). The postoperative QoR-40 score of the ERAS group was significantly higher than that of the Contr group, and the difference was statistically significant (p = 0.006). This study demonstrated that, in terms of patient-reported quality of recovery, the postoperative recovery effect of ERAS protocols in gastric cancer is significantly better than that of the traditional treatment model.

Comparing quality of recovery and satisfaction between spinal anesthesia and nerve block in orthopedic below-knee surgery: A prospective controlled trial

BACKGROUND

Postoperative quality of recovery (QoR) and patient satisfaction have gained increasing significance in medical services. This study aimed to compare these 2 parameters between 2 types of regional anesthetics (spinal anesthesia and combined sciatic-femoral nerve block) in orthopedic lower knee surgery.

METHODS

A total of 101 patients were classified into 2 groups (combined sciatic-femoral nerve block, group N; spinal anesthesia, group S) according to patient preference. In group N, sciatic and femoral nerve blocks were performed on the popliteal and groin regions, respectively, under ultrasound guidance. Spinal anesthesia was performed in group S. The primary outcomes were QoR and patient satisfaction. QoR was measured using the Korean translation of the QoR-15K. Patient satisfaction was assessed using an 11-point Likert scale (0-10) and a dichotomous question addressing anesthesia preferences for future surgeries.

RESULTS

The physical independence of the postoperative QoR-15K was significantly higher in group N than in group S (14.2 vs 12.0, P = .04). On the 11-point Likert scale, group N scored 8.8, and group S scored 7.8 (P = .001). In the dichotomous question, 93.8% of the group N and 52.8% of the group S answered that they would like to choose the same anesthesia method for the next surgery (P < .001). In addition, fewer participants in group N complained of backache than those in group S, and the time to first urination after anesthesia was shorter in group N than in group S (P = .004, <.001, respectively).

CONCLUSION

Combined sciatic-femoral nerve block may provide better physical independence and satisfaction than spinal anesthesia in orthopedic below-knee surgeries.

Quality of Postoperative Recovery in Total Intravenous Anesthesia between Remimazolam and Propofol for Intraoperative Neurophysiological Monitoring: A Prospective Double-Blind Randomized Controlled Trial

This study compared the overall postoperative recovery of patients who underwent total intravenous anesthesia with remimazolam or propofol, using the Quality of Recovery-15 questionnaire (QoR-15). Seventy-two patients who underwent spine surgery with intraoperative neurophysiological monitoring (IONM) were randomly categorized into the remimazolam group (group R) or propofol group (group P). On the first postoperative day, the QoR-15 scores for groups P and R were 114 and 112, respectively, indicating no significant difference (p = 0.691). Similarly, group-time interaction effects on QoR-15 scores were not significantly different. In the post-anesthesia care unit, the pain intensity at rest was notably higher in group P than in group R (3.0 [0.0] vs. 2.8 [0.5], respectively, p = 0.009). Although the intraoperative consumption of remifentanil was higher in group R (1452.4 µg vs. 2066.8 µg, respectively, p < 0.001), the intraoperative use of vasopressors was lower in group R (1705.6 µg vs. 286.1 µg, respectively, p < 0.001) compared to group P. Group R exhibited significantly lower variability in mean blood pressure over time compared to group P. Remimazolam was viewed as a promising intravenous agent for general anesthesia, showing potential to replace propofol in spine surgery with IONM, considering both recovery quality and intraoperative hemodynamic stability.

Effect of esketamine-based opioid-sparing anesthesia strategy on postoperative pain and recovery quality in patients undergoing total laparoscopic hysterectomy: A randomized controlled trail

Objective

Opioid-sparing anesthesia reduces intraoperative use of opioids and postoperative adverse reactions. The current study investigated the effect of esketamine-based opioid-sparing anesthesia on total laparoscopic hysterectomy patients' recovery.

Methods

Ninety patients undergoing total laparoscopic hysterectomy were randomly assigned to esketamine-based group (group K) or opioid-based group (group C). The allocation to groups was unknown to patients, surgeons, and postoperative medical staff. The inability to implement blinding for anesthesiologists was due to the distinct procedures followed by the various groups while administering drugs. The QoR-40 and VAS were used to measure recovery quality. Postoperative adverse events, perioperative opioid consumption, and intraoperative hemodynamics were secondary endpoints.

Results

There was an absence of notable discrepancy in the baseline data observed between the two groups. The QoR-40 scores exhibited greater values in group K when compared to group C on the first day following the surgical procedure (160.91 ± 9.11 vs 151.47 ± 8.35, respectively; mean difference 9.44 [95 %CI: 5.78-13.11]; P < 0.01). Within 24 h of surgery, the VAS score of group K was lower at rest and during movement. (P < 0.05 for each). Group K had much lower rates of nausea and vomiting within 24 h of surgery. (P < 0.05 for each). Group K received significantly lower total doses of sufentanil and remifentanil than group C. (17.28 ± 2.59 vs 43.43 ± 3.52; 0.51 ± 0.15 vs 1.24 ± 0.24). The proportion of patients who used ephedrine in surgery was higher in group C than in group K (P < 0.05).

Conclusions

Esketamine-based opioid-sparing anesthesia strategy is feasible and enhanced recuperation following surgery by decreasing adverse effects associated with opioids and pain scores compared to an opioid-based anesthetic regimen.

The Effect of Preoperative Education Given to Patients Who Will Have a Mastectomy: A Randomized Controlled Trial

PURPOSE

The aim of this study was to determine the effect of the education provided to patients who would undergo mastectomy on psychological well-being and quality of recovery.

DESIGN

The study had a randomized controlled trial design.

METHODS

The study was completed with 62 patients (30 in the experimental group and 32 in the control group). The experimental group received education the day before the operation, and the applications were made 3 days after the operation. A questionnaire form, the psychological well-being scale, and the quality of recovery questionnaire-40 (QoR-40) were used to collect the study data.

FINDINGS

The mean total score of the final measurement of the psychological well-being scale was higher in the experimental group than in the control group, and the difference was statistically significant. The difference between the final measurement total score average of QoR-40 and the final measurement point average of the subdimensions of the patients in the experimental and control groups was measured. The difference was statistically significant and the mean score of the experimental group was higher.

CONCLUSIONS

Education can increase the level of psychological well-being and quality of recovery in patients who undergo mastectomy. Physiological and psychological education can be used as a tool in nursing practice to improve the level of psychological well-being and quality of recovery in postoperative patients.

Comparison of Remimazolam versus Sevoflurane on the Postoperative Quality of Recovery in Cervical Spine Surgery: A Prospective Randomized Controlled Double-Blind Trial

Purpose

Remimazolam is a newly developed ultra-short-acting benzodiazepine. We compared overall functional recovery, including the postoperative Quality of Recovery-15 (QoR-15) questionnaire scores, between balanced inhalational anesthesia using sevoflurane and total intravenous anesthesia (TIVA) with remimazolam in patients undergoing anterior cervical discectomy and fusion (ACDF).

Patients and Methods

Seventy-two patients were randomized to the remimazolam (group R) or sevoflurane (group S) group. The primary outcome was the total QoR-15 score on postoperative day (POD) 1. We also assessed the total QoR-15 score on POD2, sub-scores of the QoR-15, perioperative parameters, and postoperative recovery profiles. Group-time interaction effects on the QoR-15 and its sub-scores were analyzed using a linear mixed model.

Results

The total QoR-15 score on POD1 (120.2 in group R vs 114.3 in group S, P=0.189) was not statistically different between the groups. There were no significant group-time interaction effects on total QoR-15 scores. Instead, patients in group R showed significantly better sub-scores in psychological and postoperative nausea and vomiting (PONV) items on POD1, as well as a lower degree of PONV, than those in group S. Among the five dimensions of the QoR-15, a significant group-time interaction effect was observed for psychological support. Group R showed significantly less changeability in blood pressure and heart rate with a lower dose of intraoperatively administered vasopressor than group S.

Conclusion

Considering QoR-15, including PONV reduction, and intraoperative hemodynamic stability, remimazolam can be used as the novel and safe anesthetic agent for maintaining general anesthesia instead of sevoflurane in patients undergoing ACDF.

Effects of Scalp Nerve Block on the Quality of Recovery after Minicraniotomy for Clipping of Unruptured Intracranial Aneurysms : A Randomized Controlled Trial

OBJECTIVE

This study compared the quality of recovery (QoR) after minicraniotomy for clipping of unruptured intracranial aneurysms (UIAs) between patients with and without scalp nerve block (SNB).

METHODS

Patients were randomly assigned to the SNB (SNB using ropivacaine with epinephrine, n=27) and control (SNB using normal saline, n=25) groups. SNB was performed at the end of surgery. To assess postoperative QoR, the QoR-40, a patient-reported questionnaire, was used. The QoR-40 scores were measured preoperatively, 1-3 days postoperatively, at hospital discharge, and 1 month postoperatively. Pain and intravenous patient-controlled analgesia (IV-PCA) consumption were evaluated 3, 6, 9, and 12 hours and 1-3 days postoperatively.

RESULTS

All QoR-40 scores, including those measured 1 day postoperatively (primary outcome measure; 155.0 [141.0-176.0] vs. 161.0 [140.5-179.5], p=0.464), did not significantly differ between the SNB and control groups. The SNB group had significantly less severe pain 3 (numeric rating scale [NRS]; 3.0 [2.0-4.0] vs. 5.0 [3.5-5.5], p=0.029), 9 (NRS; 3.0 [2.0-4.0] vs. 4.0 [3.0-5.0], p=0.048), and 12 (NRS; 3.0 [2.0-4.0] vs. 4.0 [3.0-5.0], p=0.035) hours postoperatively. The total amount of IV-PCA consumed was significantly less 3 hours postoperatively in the SNB group (2.0 [1.0-4.0] vs. 4.0 [2.0-5.0] mL, p=0.044).

CONCLUSION

After minicraniotomy for clipping of UIAs, SNB reduced pain and IV-PCA consumption in the early postoperative period but did not improve the QoR-40 scores.

Psychometric evaluation of a quality of recovery score for the postanesthesia care unit-A preliminary validation study

INTRODUCTION

Patients' perception of postoperative recovery is a key aspect of perioperative care. Self-reported quality of recovery (QoR) has evolved as a relevant endpoint in perioperative research. Several psychometric instruments have been introduced to assess self-reported recovery 24 hours after surgery. However, there is no questionnaire suitable for use in the postanesthesia care unit (PACU). We aimed to develop and psychometrically evaluate a QoR questionnaire for the PACU (QoR-PACU).

METHODS

The QoR-PACU was developed in German language based on the 40-item QoR-40 questionnaire. Between March and November 2020, adult patients scheduled for elective urologic surgery completed the QoR-PACU preoperatively and during the PACU stay. We evaluated feasibility, validity, reliability, and responsiveness.

RESULTS

We included 375 patients. After two piloting phases including 72 and 48 patients, respectively, we administered the final version of the QoR-PACU to 255 patients, with a completion rate of 96.5%. Patients completed the QoR-PACU at a median of 125.0 (83.0; 156.8) min after arrival in the PACU. Construct validity was good with postoperative QoR-PACU sum scores correlating with age (r = 0.23, 95% CI: 0.11 to 0.35, p < 0.001), length of PACU stay (r = -0.15, 95%CI: -0.27 to -0.03, p = 0.02), pain in the PACU (r = -0.48, 95% CI: -0.57 to -0.37, p < 0.001) and piritramide dose administered (r = -0.29, 95% CI: -0.40 to -0.17, p < 0.001). Cronbach's alpha was 0.67 (95% CI: 0.61-0.73) with moderate test-retest reliability (ICC of 0.67, 95% CI: 0.38 to 0.83). Cohen's effect size was 3.08 and the standardized response mean was 1.65 indicating adequate responsiveness.

CONCLUSION

The assessment of QoR in the early postoperative period is feasible. We found high acceptability, good validity, adequate responsiveness, and moderate reliability. Future studies should evaluate the psychometric properties of the QoR-PACU in more heterogeneous patient populations including female and gender-diverse patients with varying degress of perioperative risk.

Appropriateness of the anxiety subscale of the Hospital Anxiety and Depression Scale for Koreans to measure preoperative anxiety and the effect of preoperative anxiety on postoperative quality of recovery

BACKGROUND

The reliability and validity of the anxiety subscale of the Hospital Anxiety and Depression Scale for Koreans (K-HADS-A) has not been studied in Korean surgical patients. This study aimed to validate the usefulness of K-HADS-A for measuring preoperative anxiety in Korean surgical patients. Additionally, the effect of preoperative anxiety on postoperative quality of recovery was evaluated.

METHODS

Preoperative anxiety in 126 inpatients with planned elective surgery was measured using the K-HADS-A. The postoperative quality of recovery was measured using the Korean version of the Quality of Recovery-15. The validity and reliability of the K-HADS-A were evaluated. The differences in quality of recovery on the first and seventh day postoperatively were then compared between the anxious and non-anxious groups.

RESULTS

There was a statistical correlation between the K-HADS-A and Anxiety Likert Scale. The goodness-of-fit indices of the structural equation model showed how well the data from the K-HADS-A match their concept. The Kaiser-Meyer-Olkin value was 0.848, and the P value of Bartlett's test of sphericity was < 0.001. Cronbach's alpha was high at 0.872. The K-HADS-A had an acceptable level of validity and reliability. Postoperative quality of recovery was significantly lower in the anxious group (postoperative day 1: t = 2.058, P = 0.042; postoperative day 7: t = 3.430, P = 0.002).

CONCLUSIONS

The K-HADS-A is an acceptable tool for appropriately assessing preoperative anxiety in Korean surgical patients. Assessing preoperative anxiety is valuable, because preoperative anxiety affects the postoperative quality of mental and physical recovery.

Analgesic effects of combined transversus abdominis plane block and intramuscular electrical stimulation in patients undergoing cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy: a randomized controlled trial

BACKGROUND

To evaluate the analgesic efficacy of a four-quadrant transversus abdominis plane (4QTAP) block and a combination of 4QTAP block with needle electrical twitch and intramuscular electrical stimulation (NETOIMS) in patients undergoing cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC).

MATERIALS AND METHODS

Eighty-one patients who underwent CRS followed by HIPEC were included in this study. Patients were randomly assigned to one of three groups: group 1 (intravenous patient-controlled analgesia, control group), group 2 (preoperative 4QTAP block), and group 3 (preoperative 4QTAP block and postoperative NETOIMS). The primary study endpoint was the pain score assessed by the visual analog scale (VAS: 0, no pain; 10, worst imaginable pain) on postoperative day (POD) 1.

RESULTS

The VAS pain score on POD 1 was significantly lower in group 2 than in group 1 (6.0±1.7 and 7.6±1.9, P =0.004), whereas that in group 3 was significantly lower than that in groups 1 and 2 ( P <0.001 and P =0.004, respectively). Opioid consumption and nausea and vomiting incidence during POD 7 were significantly lower in group 3 than in groups 1 and 2. Gait speed and peak cough flow on POD 4 and 7, as well as the quality of recovery (QoR)-40 score on POD 4, were significantly higher in group 3 than in groups 1 and 2.

CONCLUSIONS

The combination of a 4QTAP block with NETOIMS provided more effective analgesia than a 4QTAP block alone after CRS, followed by HIPEC, and enhanced functional restoration and quality of recovery.

Functional recovery with peripheral nerve block versus general anesthesia for upper limb surgery: a systematic review

BACKGROUND

Peripheral nerve block is a common anesthetic technique used during orthopedic upper limb surgery. Injection of local anesthetics around the target nerve inhibits the action of voltage-dependent sodium channels, inhibiting neurotransmission of pain impulses and providing motor immobility. Compared to general anesthesia, it could improve functional recovery by inhibiting nociceptive impulses and inflammation, thus reducing postoperative pain and immobilization and improving postoperative rehabilitation. This systematic review evaluates the impact of peripheral nerve block versus general anesthesia on postoperative functional recovery following orthopedic upper limb surgery.

METHODS

We searched CENTRAL, MEDLINE, CINHAL, EMBASE, and Scopus trial databases from inception until September 2021 for studies comparing peripheral nerve block to general anesthesia. We collected data on functional recovery, range of motion, patient satisfaction, quality of life, and return to work. We pooled studies using a random-effects model and summarized the quality of evidence with the GRADE approach.

RESULTS

We assessed 373 citations and 19 full-text articles for eligibility, and included six studies. Six studies reported on functional recovery, but failed to detect a significant superiority of peripheral nerve block over general anesthesia (3 RCT studies, N = 160; SMD -0.15; CI at 95% -0.60-0.3; I² = 45%; p = 0.07; low quality of evidence and 3 observational studies, N = 377; SMD -0.35; CI at 95% -0.71-0.01; I² = 64%; p = 0.06; very low quality of evidence).

CONCLUSIONS

Current literature is limited and fails to identify the benefit of peripheral nerve block on functional recovery. More studies are needed to assess the impact on long-term recovery. Considering the potential impact on clinical practice and training, a prospective study on functional recovery is ongoing (NCT04541745).

Comparison of Postoperative Recovery between Balanced and Total Intravenous Anesthesia in Patients Undergoing Off-Pump Coronary Artery Bypass (OPCAB) Surgery: A Prospective, Single-Blind Randomized Study

Recovery after anesthesia has a significant impact on a patient's return to daily life. This study was performed to compare the postoperative quality of recovery according to the method of anesthesia administered among patients undergoing OPCAB using the Korean version of the Quality of Recovery-40 (QoR-40K) questionnaire. This single-blind, prospective study (trial number: KCT0004726) was performed using a population of 102 patients undergoing OPCAB under general anesthesia. The patients were randomly assigned to one of two groups using a computer-generated list: a total intravenous anesthesia group (Group T) and a balanced anesthesia group (Group B). The QoR-40K score was measured preoperatively and at 24 and 48 h after extubation. There was no significant difference in the QoR-40K scores between the groups at 24 and 48 h after extubation. In addition, there were no significant differences between groups with respect to any of the five dimensions of QoR-40K at 24 and 48 h after extubation. Finally, there were no differences in the postoperative opioid consumption, time to extubation, or length of hospital stay. In this study, there was no difference in the QoR-40K score at 24 h after extubation between Groups T and B. Therefore, both methods of anesthesia are suitable for use when performing OPCAB.

Effect of co-administration of intravenous lidocaine and dexmedetomidine on the recovery from laparoscopic hysterectomy: a randomized controlled trial

BACKGROUND

Some evidences have reported that intravenous lidocaine and dexmedetomidine alone can improve the quality of recovery after surgery. The main purpose of our study to explore whether co-administration of lidocaine and dexmedetomidine infusion could further improve the quality of recovery after laparoscopic hysterectomy compared to either lidocaine or dexmedetomidine administration.

METHODS

A total of 160 subjects were randomly allocated to four groups: the control group (group C) received an equal volume of normal saline, the lidocaine group (group L) received lidocaine (1.5 mg/kg for bolus over 10 min before induction of anesthesia, 1.5 mg/kg/h for continuous infusion), the dexmedetomidine group (group D) received dexmedetomidine (0.5 µg/kg for bolus over 10 min before induction of anesthesia, 0.4 µg/kg/h for continuous infusion), the lidocaine plus dexmedetomidine group (group LD) received lidocaine (1.5 mg/kg for bolus over 10 min before induction of anesthesia, 1.5 mg/kg/h for continuous infusion) and dexmedetomidine combined infusion (0.5 µg/kg for bolus over 10 minutes before induction of anesthesia, 0.4 µg/kg/h for continuous infusion). The primary endpoint was the quality of recovery-40 (QoR-40) scores on postoperative day 1 (POD1). The quality of sleep on POD1, remifentanil total dose, visual analog scale (VAS) pain scores, the number of patients with self-press the pump, time to open eye and extubation, length of postanesthesia care unit (PACU) stay, the incidence of intraoperative bradycardia, hypotension, arrhythmias, hypoxemia in the PACU, and nausea or vomiting within 24 h after surgery were regarded as the secondary outcomes.

RESULTS

The total QoR-40 scores were significantly increased in groups L, D, and LD on POD1 compared with group C (all P<0.05). The total QoR-40 scores were the highest in group LD on POD1 compared to other three groups (all P<0.001). Sleep quality was significantly improved in group LD compared to other three groups on POD1 (all P<0.05). The VAS pain scores were obviously reduced at 8 h in group L and at 4, 8 h in group D after surgery compared to group C and were the lowest in group LD (all P<0.05). The number of patients with self-press the pump was significantly reduced in groups D and LD compared to group C (8(20.0%) and 27(67.5%), P<0.001; 2(5.0%) and 27(67.5%), P<0.001, respectively). Length of PACU stay significantly prolonged in groups D (21.7±3.0) and LD (25.5±4.0) compared to group C (19.6±3.3) (P=0.028, P<0.001). The incidence of intraoperative bradycardia was significantly higher in groups D and LD than in groups C and L (all P<0.001). The rate of hypoxemia was higher in groups D (55.0%) and LD (70.0%) than in groups C (15.0%) and L (20.0%) (all P<0.05). The incidence of nausea was lower in group LD (10.0%) than in group C (37.5%) (P<0.05).

CONCLUSIONS

Co-administration of lidocaine plus dexmedetomidine infusion improved to some extent the quality of recovery on POD1 compared to lidocaine and dexmedetomidine alone, but it significantly increased the incidence of intraoperative bradycardia and hypoxemia in the PACU, and prolonged the length of PACU stay.

Effect of transversus abdominis plane block on the quality of recovery in laparoscopic nephrectomy: A prospective double-blinded randomized controlled clinical trial

BACKGROUND

Poorly controlled acute postoperative pain after laparoscopic nephrectomy may adversely affect surgical outcomes and increase morbidity rates. In addition, excessive use of opioids during surgery may slow postoperative endocrine and metabolic responses and cause opioid-related side effects and opioid-induced hyperalgesia. The purpose of this study was to evaluate the effect of ultrasound-guided transversus abdominis plane (TAP) block on the postoperative quality of recovery and intraoperative remifentanil requirement in laparoscopic nephrectomy.

METHODS

Sixty patients who underwent laparoscopic nephrectomy were randomly divided into 2 groups: TAP and Control groups. After induction of anesthesia and before awakening from anesthesia, the TAP group was administered 40 mL of 0.375% ropivacaine and the Control group was administered 40 mL of normal saline to deliver ultrasound-guided TAP block using 20 mL of each of the above drugs. The main objectives of this study were to evaluate the effect of the TAP block on quality of recovery using the Quality of Recovery 40 (QoR-40) questionnaire and assessments of intraoperative remifentanil requirement. In addition, to evaluate the postoperative analgesic effect of the TAP block, the total usage time for patient-controlled analgesia (PCA) and the number of PCA bolus buttons used in both groups were analyzed.

RESULTS

The QoR-40 score, measured when visiting the ward on the third day after surgery, was significantly higher in the TAP group (171.9 ± 23.1) than in the Control group (151.9 ± 28.1) (P = .006). The intraoperative remifentanil requirement was not significantly different between the groups (P = .439). In the TAP group, the frequency of bolus dose accumulation at 1, 2, 3, 6, 12, 24, 48, and 72 hours after surgery was low enough to show a significant difference, and the total usage time for PCA was long enough to show a significant difference.

CONCLUSION

In conclusion, we determined that ultrasound-guided TAP block during laparoscopic nephrectomy improves the quality of postoperative recovery and is effective for postoperative pain control but does not affect the amount of remifentanil required for adequate anesthesia during surgery.

Effect of Erector Spinae Plane Block on Postoperative Pain after Laparoscopic Colorectal Surgery: A Randomized Controlled Study

The erector spinae plane (ESP) block can be used to reduce pain and opioid requirements after abdominal surgery. We evaluated the effect of the ESP block on postoperative pain score, analgesic use, and quality of recovery (QoR) score in patients undergoing laparoscopy. Fifty-nine patients undergoing elective laparoscopic colorectal surgery were randomly assigned to control (n = 30) or ESPB (n = 29) groups after anesthesia induction. In the ESPB group, an ultrasound-guided ESP block was performed immediately after induction using 20 mL of 0.5% ropivacaine bilaterally. The primary outcome was the postoperative pain score, which was evaluated using the 11-point numeric rating scale (NRS) (0 = no pain, 10 = worst imaginable pain), in the recovery room. NRS “at rest” and “on cough” and total dose of fentanyl rescue (in the recovery room) as well as NRS “at rest” and the cumulative administered fentanyl dose of patient-controlled analgesia (24 h post-surgery) were significantly lower in the ESPB group than in the control group. The postoperative QoR score did not differ between the groups. Bilateral ESP block after induction reduced pain scores and opioid requirements for 24 h postoperatively but did not improve the QoR in patients undergoing laparoscopic colorectal surgery.

The effect of newly designed dual-channel elastomeric pump for intravenous patient-controlled analgesia after total laparoscopic hysterectomy: a randomized, double-blind, prospective study

BACKGROUND

A newly designed intravenous patient-controlled analgesia (PCA) device with a dual-channel elastomeric infusion pump has been recently introduced. One channel is a continuous line with a constant flow rate basal infusion, while the other channel has an adjustable flow rate and bolus function and is labeled as a selector-bolus channel. This study compared dual and single-channel intravenous PCA in terms of clinical effect and quality of recovery.

METHODS

Eighty-four patients undergoing total laparoscopic hysterectomy were randomly allocated to a 1-channel group (n = 41) or a 2-channel group (n = 43). Only the selector-bolus channel was utilized, but the continuous channel was not utilized in the 1-channel group, but both channels were utilized in the 2-channel group. In the 1-channel group, 16 μg/kg of fentanyl, 2 mg/kg of ketorolac, and 12 mg of ondansetron with normal saline were administered to the selector-bolus channel and normal saline only in the continuous channel for blinding. In the 2-channel group, 16 μg/kg of fentanyl was administered to the selector-bolus channel, and ketorolac (2 mg/kg) and ondansetron (12 mg) were administered via the continuous channel. The quality of recovery was evaluated preoperatively and 24 h postoperatively using the Quality of Recovery-40 (QoR-40). Cumulative PCA consumption, postoperative pain rated using the numeric rating scale (NRS; during rest/cough), and postoperative nausea were evaluated 6, 12, 24, 36, and 48 h after surgery. Incidence of vomiting and use of antiemetics and rescue analgesics was measured.

RESULTS

The 24-h postoperative QoR-40 score was higher in the 2-channel group than in the 1-channel group (P=0.031). The incidence of nausea at 12 h and 36 h was significantly higher in the 1-channel group (P=0.043 and 0.040, respectively), and antiemetic use was more frequent in the 1-channel group (P=0.049). Patient satisfaction was higher in the 2-channel group (P=0.036). No significant differences were observed in pain scores during resting/cough or cumulative PCA consumption.

CONCLUSIONS

The 2-channel PCA showed better patient satisfaction with higher QoR-40 during the recovery compared with the 1-channel PCA. Better satisfaction was associated with lower nausea and reduced rescue antiemetics by maintaining the infusion of adjuvant analgesic agents and antiemetic agents constantly by utilizing dual channels.

Effect of Low or High Pressure Alveolar Recruitment Maneuver on Postoperative Pain and Quality of Recovery in Patients with Obesity Undergoing Laparoscopic Sleeve Gastrectomy

Background: This study aimed to evaluate whether a low- or high-pressure alveolar recruitment maneuver (ARM) might reduce postoperative pain and improve the quality of recovery after laparoscopic bariatric surgery. Methods: 90 patients with a body mass index > 30 kg/m2 scheduled for laparoscopic sleeve gastrectomy were randomly assigned to control (n = 30), low ARM (n = 30), or high ARM groups (n = 30). For the low and high ARM groups, ARM was repeated five times to hold the peak airway pressure at 30 cmH2O and 60 cmH2O for 5 s, respectively, before removal of the trocar. Conventional methods to reduce post-laparoscopic pain, such as intraperitoneal saline irrigation, hemovac drainage, and gentle abdominal compression were performed in all patients, regardless of the assigned group. Results: Shoulder and surgical site pain scores 24 h postoperatively and rescue meperidine requirement were similar between the groups (p = 0.141, 0.101, and 0.82, respectively). The quality of recovery 40 (QoR40) score 24 h postoperatively was similar between the groups (p = 0.755). Postoperative pulmonary complications were similar between the groups (p = 0.124). Conclusion: Application of a low- or high-pressure ARM in addition to conventional methods to remove remnant peritoneal CO2 gas did not reduce postoperative shoulder or surgical site pain or improve the quality of recovery after laparoscopic sleeve gastrectomy.

The Effect of Opioid-Free Anesthesia on the Quality of Recovery After Gynecological Laparoscopy: A Prospective Randomized Controlled Trial

Purpose

Opioid-free anesthesia (OFA) is an emerging technique that eliminates intraoperative use of opioids and is associated with lower postoperative opioid consumption and reduced adverse postoperative events. The present study investigated the effect of OFA on the quality of recovery in patients undergoing gynecological laparoscopy.

Patients and Methods

Seventy-five adult patients undergoing elective gynecological laparoscopy were randomly assigned to the OFA group with dexmedetomidine and lidocaine or the remifentanil-based anesthesia (RA) group with remifentanil. Patients, surgeons, and medical staff members providing postoperative care and assessing outcomes were blinded to group allocation. The anesthesiologist performing general anesthesia could not be blinded due to the different drug administration protocols by groups. The primary outcome was the quality of recovery measured using the Quality of Recovery-40 (QoR-40) questionnaire. Secondary outcomes were postoperative pain score, intraoperative and postoperative adverse events, and stress hormones levels.

Results

The patients in both groups had comparable baseline characteristics. The QoR-40 score on postoperative day 1 was significantly higher in the OFA group than in the RA group (155.9 ± 21.2 in the RA group vs 166.9 ± 17.8 in the OFA group; mean difference: −11.0, 95% confidence interval: −20.0, −2.0; p = 0.018). The visual analog scale score at 30 min after surgery was significantly lower in the OFA group than in the RA group (6.3 ± 2.3 in the RA group vs 4.1 ± 2.1 in the OFA group; p < 0.001). The incidences of nausea and shivering in the post-anesthetic care unit were also significantly lower in the OFA group (p = 0.014 and 0.025; respectively). Epinephrine levels were significantly lower in the OFA group (p = 0.002).

Conclusion

OFA significantly improved the quality of recovery in patients undergoing gynecological laparoscopy.

Quality of recovery in patients administered remimazolam versus those administered an inhalant agent for the maintenance of general anesthesia: a randomized control trial

Background

Remimazolam is a novel intravenous benzodiazepine that is appropriate for the maintenance of anesthesia. Quality of recovery is an important component of health care quality, but there is no published randomized control trial focused on the quality of recovery in patients undergoing total intravenous anesthesia with remimazolam.

Methods

This parallel-group, single-blind randomized control trial at a tertiary care medical center in South Korea was conducted to determine the difference in the quality of recovery between the patients administered remimazolam and those administered an inhalant anesthetic agent. A total of 168 patients aged 19–65 years who underwent elective laparoscopic cholecystectomy or robotic gynecologic surgery were considered for enrollment. Randomization was performed using sealed envelopes containing computer-generated random allocation sequences.

Remimazolam was administered for the maintenance of anesthesia in the remimazolam group (Group R), and desflurane was administered in the desflurane group (Group D). The induction protocol and the target value of the bispectral index were identical in both groups. Patients were blinded to the drug that was administered until they finished the postoperative questionnaire.

The main outcome measure was the decrement of the QoR-40 score on postoperative day 1 compared to the QoR-40 score on the day before surgery.

Results

A total of 165 patients were analyzed. The preoperative and postoperative global QoR-40 scores were 183 and 152 (IQR 173–192 and 136–169), respectively. The perioperative decrement of the global QoR-40 score was 29.96 ± 22.49. The decrement of the QoR-40 score was smaller in Group R than in Group D (26.99 versus 32.90, respectively; mean difference 5.91, 95% confidence interval -0.96–12.79). After adjustment for sex, the type of surgery and surgical time, the administration of remimazolam resulted in a 7.03-point (95% CI 0.35–13.72) less decrement of the QoR-40 score than desflurane. There were no severe adverse events in either group.

Conclusion

Total intravenous anesthesia maintained with remimazolam provides a better quality of recovery than anesthesia maintained with an inhalant agent in patients undergoing laparoscopic surgery. Additionally, postoperative nausea and vomiting were largely reduced with remimazolam.

Effect of Preventive Analgesia with Nalbuphine and Dexmedetomidine in Endoscopic Sinus Surgery

Background

The study was to assess the efficacy and safety of nalbuphine combined with dexmedetomidine for preventive analgesia in endoscopic sinus surgery.

Methods

110 patients with deviation of the nasal septum were randomized into the nalbuphine group (group N), dexmedetomidine combined with nalbuphine group (group DN), and saline group (group C). Fifteen minutes before the induction of anesthesia, patients in group N were injected nalbuphine 0.2 mg/kg intravenously; patients in group DN received intravenous infusion of dexmedetomidine 0.5 μg/kg and injection of nalbuphine 0.2 mg/kg; patients in group C received 0.9% saline. Mean arterial pressure (MAP), heart rate (HR), numerical rating scale (NRS) scores, quality of recovery-40 (QoR-40) scores, the need for remedial analgesia, the consumption of remifentanil and propofol, and the incidence of adverse reactions were recorded.

Results

MAP, HR, and NRS scores of the DN group were significantly lower and the QoR-40 scores were higher than those of groups N and C (P < 0.001). The need for remedial analgesia, the consumption of remifentanil and propofol, and the incidence of nausea in the DN group were the lowest among the three groups (P < 0.001).

Conclusion

Preventive analgesia with nalbuphine and dexmedetomidine in endoscopic sinus surgery can not only maintain hemodynamic stability but also reduce intraoperative anesthetic dosage, postoperative pain, and improve the quality of postoperative recovery without affecting the revival and extubation time.

Validation and Clinical Utility of the Korean Version of the Obstetric Quality-of-Recovery Score (ObsQoR-11) Following Elective Cesarean Section: A Prospective Observational Cohort Study

The Obstetric Quality of Recovery (ObsQoR-11) score is a new scoring tool that assesses maternal recovery after cesarean section (CS). We aimed to validate the translated Korean version of ObsQoR-11 (ObsQoR-11K) after elective CS. We validated ObsQoR-11K between March 2021 to August 2021. Validity (convergent, discriminant, and construct), reliability (Cronbach’s α, inter-item, split-half, and test-retest correlation), responsiveness, and clinical feasibility (recruitment rate and time for ObsQoR-11K completion) of ObsQoR-11K were evaluated. One hundred and twenty women completed the ObsQoR-11K 24 h after CS, and 24 women repeated it 25 h after CS. We found good convergent validity between the ObsQoR-11K score and the global health numerical rating scale (NRS) (ρ = 0.73 (95% CI 0.64 to 0.81); p < 0.001). The ObsQoR-11K score discriminated well between good (NRS ≥ 70 mm, n = 68, 69.6 ± 13.7) and poor recovery (NRS < 70 mm, n = 52, 50.6 ± 12.6, p < 0.001). The ObsQoR-11K score showed acceptable internal consistency (Cronbach’s α = 0.78), split-half reliability (0.89), intra-class correlation > 0.4, and no floor or ceiling effect. Of the participants, 100% completed the ObsQoR-11K and median (IQR) time for ObsQoR-11K completion was 81 s (66–97.5 s). ObsQoR-11K is a valid and reliable scoring tool for assessing maternal recovery after elective CS in Korean women.

Impact of Bilateral Subcostal Plus Lateral Transversus Abdominis Plane Block on Quality of Recovery After Laparoscopic Cholecystectomy: A Randomized Placebo-Controlled Trial

BACKGROUND

Previous research has not evaluated the potential effect of transversus abdominis plane (TAP) block on quality of recovery following laparoscopic cholecystectomy. Therefore, we investigated whether addition of the bilateral subcostal and lateral TAP (bilateral dual TAP [BD-TAP]) blocks to multimodal analgesia would improve the quality of recovery as assessed with the Quality of Recovery-40 (QoR-40).

METHODS

Patients age 18 to 60 years who were scheduled to undergo elective laparoscopic cholecystectomy were randomized to the BD-TAP or control group. The BD-TAP group received the BD-TAP block with multimodal analgesia under general anesthesia, using 0.25% ropivacaine, and the control group was treated with the same method, except that they received the sham block using 0.9% normal saline. Both groups had the same multimodal analgesia regimen, consisting of intravenous dexamethasone, propacetamol, ibuprofen, and oxycodone. The primary outcome was the QoR-40 score at 24 hours after surgery. Data were analyzed using the independent t test, Mann-Whitney U test, χ2 test, and Fisher exact test.

RESULTS

Thirty-eight patients in each group were recruited. The mean QoR-40 score decreased by 13.6 (95% confidence interval [CI], 8.3-18.8) in the BD-TAP group and 15.6 (95% CI, 6.7-24.5) in the control group. The postoperative QoR-40 score at 24 hours after surgery did not differ between the 2 groups (BD-TAP group, median [interquartile range], 170.5 [152-178]; control group, 161 [148-175]; median difference, 3 [95% CI, -5 to 13]; P = .427). There were no differences between the 2 groups in the pain dimension of the QoR-40: 30.5 (95% CI, 27-33) in the BD-TAP group and 31 (95% CI, 26-32) in the control group; median difference was 0 (95% CI, -2 to 2); P = .77.

CONCLUSIONS

Our results indicate that the BD-TAP block does not improve the quality of recovery or analgesic outcomes following laparoscopic cholecystectomy. Our results do not support the routine use of the BD-TAP block for this surgery.

Comparison of continuous and single interscalene block for quality of recovery score following arthroscopic rotator cuff repair

BACKGROUND

Continuous interscalene brachial plexus block (CISB) is well known to reduce postoperative pain and to improve patient satisfaction. However, the effect of CISB on the quality of postoperative recovery is unknown. We Compared the quality of recovery from arthroscopic rotator cuff repair in patients who received CISB or single interscalene brachial plexus block (SISB).

METHODS

This prospective non-randomized controlled trial with propensity score matching enrolled 134 patients undergoing arthroscopic surgery for rotator cuff repair. Each patient received an interscalene block before surgery. One group had a catheter insertion 30 min after the end of surgery and started patient-controlled regional analgesia (PCRA, n = 49). The other group received intravenous patient-controlled analgesia (IV-PCA, n = 85). The primary outcome was the quality of recovery (QoR-40) score. Also, postoperative analgesia, sleep quality, and postoperative complications were evaluated.

RESULTS

The two groups had similar QoR-40 score on postoperative day-1 (POD1), but the PCRA group had a significantly greater QoR-40 score on POD2 (156.0, IQR: 143.0, 169.0 vs. 171.0, IQR: 159.0, 178.0; p < 0.001). The IV-PCA group received more analgesics during the 2 days after surgery, especially during night-time, and had a higher prevalence of sleep disturbances. The time to first additional analgesics request was significantly longer in PCRA group (14 hours, 95% CI: 13-16 vs. 44 hours, 95% CI: 28-not applicable). The incidence of postoperative nausea and vomiting significantly lower in the PCRA group (16.3% vs 46.9%, p = 0.002).

CONCLUSION

CISB showed a higher quality of recovery score than SISB with IV-PCA in arthroscopic rotator cuff repair, probably related to the effective analgesia, improved sleep quality, and reduced opioid-related complications.

CROATIAN VERSION OF THE QUALITY OF RECOVERY QUESTIONNAIRE (QoR-40): TRANSCULTURAL ADAPTATION AND VALIDATION

The Quality of Recovery-40 (QoR-40) questionnaire is a psychometric instrument designed to quantify postoperative recovery. It has been translated and validated in several countries but not in Croatia. The aim was to translate, cross-culturally adapt, and validate Croatian version of the QoR-40. The QoR-40 was translated from English by two independent translators, back-translated by a native speaker, and approved by an expert committee. The questionnaire was administered to 106 patients who underwent general anesthesia before elective spinal surgery, post-surgery in the operating room, and 30 days after surgery. Internal consistency was assessed using the Cronbach's alpha coefficient. Construct validity was assessed by evaluating correlation between the QoR-40 and hand grip strength. The mean preoperative global QoR-40 score was 177.6 (95% CI 174.9-180.3) and postoperative 168.9 (95% CI 165.8-171.9); the mean change was -8.8 (95% CI -11.9 to -5.6). Internal consistency was good for global QoR-40 score (Cronbach α=0.896), acceptable across all domains (8>α≥7). There was a significant correlation between grip strength and total QoR-40 score, pain, and physical independence, but not with other domains. In conclusion, the Croatian version of the QoR-40 has acceptable properties and can be used in the assessment of postoperative recovery in Croatian patients.

Pre-emptive multimodal analgesic bundle with transversus abdominis plane block enhances early recovery after laparoscopic cholecystectomy

BACKGROUND

As postoperative pain after laparoscopic cholecystectomy may delay recovery and discharge, a multimodal and pre-emptive analgesic approach is necessary. This study demonstrated that a multimodal analgesic bundle improves postoperative recovery, using the Quality of Recovery-40K (QoR-40K) questionnaire during the first 24 h after laparoscopic cholecystectomy.

METHODS

In this prospective non-randomized study with two parallel groups, 80 patients undergoing laparoscopic cholecystectomy were allocated into either the multimodal analgesia group or the conventional analgesia group. The multimodal analgesia group received a pre-emptive analgesic bundle (preoperative intravenous administration of paracetamol, ketorolac, and dexamethasone, and a posterior approach to the transversus abdominis plane block), while the conventional analgesia group did not. The primary outcome was the QoR-40K score during the first 24 h after surgery. Secondary outcomes were the peak visual analog scale pain score at rest and the incidence rates of rescue analgesic use and nausea/vomiting during the first 24 h after surgery.

RESULTS

The QoR-40K score was higher in the multimodal analgesia group than in the conventional analgesia group (196 [190-199] vs. 182 [172-187], p < 0.001). The peak visual analog scale pain score was significantly lower in the multimodal analgesia group than in the conventional analgesia group. Multimodal analgesia also reduced the incidence rates of rescue analgesic use and postoperative nausea/vomiting (22.5% [95% CI, 9.6-35.4%] vs. 55.0% [39.6-70.4%], p = 0.003), compared to conventional analgesia.

CONCLUSIONS

Multimodal analgesia significantly improves the quality of early postoperative recovery after laparoscopic cholecystectomy, as shown by the QoR-40K score.

The effect of opioid-free anesthesia on the quality of recovery after gynecological laparoscopy: study protocol for a prospective randomized controlled trial

BACKGROUND

Because of the indiscriminate use of opioids during the perioperative period, opioid-free anesthesia (OFA) has been increasingly required. Nevertheless, the studies on the detailed techniques and effects of OFA are not sufficient. The Quality of Recovery-40 (QoR-40) questionnaire is a validated assessment tool for measuring recovery from general anesthesia. However, no study has used the QoR-40 to determine if OFA leads to better recovery than standard general anesthesia. Therefore, we aim to perform this study to determine the effects of OFA using dexmedetomidine and lidocaine on the quality of recovery as well as the various postoperative outcomes.

METHODS

The participants (n = 78) will be allocated to one of the two groups; the study group will receive bolus and infusion of dexmedetomidine and lidocaine, and the control group will receive remifentanil infusion during general anesthesia for gynecological laparoscopy. The other processes including anesthetic and postoperative care will be performed similarly in the two groups. Intraoperative hemodynamic, anesthetic, and nociceptive variables will be recorded. Postoperative outcomes such as QoR-40, pain severity, and opioid-related side effects will be assessed. Additionally, an ancillary cytokine study (inflammatory cytokine, stress hormone, and reactive oxygen species) will be performed during the study period.

DISCUSSION

This will be the first study to determine the effect of OFA, using the combination of dexmedetomidine and lidocaine, on the quality of recovery after gynecological laparoscopy compared with standard general anesthesia using remifentanil. The findings from this study will provide scientific and clinical evidence on the efficacy of OFA.

The Analgesic Efficacy of Nefopam in Patient-Controlled Analgesia after Laparoscopic Gynecologic Surgery: A Randomized, Double-Blind, Non-Inferiority Study

Opioid-sparing effects of nefopam during patient-controlled analgesia (PCA) are well demonstrated. We hypothesized that postoperative pain control with an opioid-equivalent dose of nefopam as a single analgesic agent for PCA would not be inferior to fentanyl in laparoscopic gynecologic surgery. In total, 135 patients were randomly assigned to the N (nefopam 200 mg), NF (fentanyl 500 mcg + nefopam 100 mg), and F (fentanyl 1000 mcg) groups (n = 45 patients per group). The primary outcome was the numerical rating scale (NRS) score at rest at 6 h postoperatively, and the non-inferiority limit was set to 1. Secondary outcomes were pain severity and incidence of nausea and vomiting for 48 h postoperatively. Mean differences (MD) in primary outcome between the N and F groups were 0.4 (95% confidence interval (CI) −0.5 to 1.3). The upper limit of 95% CI exceeded the non-inferiority limit. The N group showed higher pain scores than the NF group (MD, 1.1; 95% CI, 0.3–1.9) in pairwise comparisons. No significant intergroup differences were observed in the cumulative dose of PCA usage and incidence of postoperative nausea and vomiting (PONV). In laparoscopic gynecological surgery, nefopam alone showed limited efficacy for postoperative pain control.

Quality of Recovery after Laparoscopic Cholecystectomy Following Neuromuscular Blockade Reversal with Neostigmine or Sugammadex: A Prospective, Randomized, Controlled Trial

The risk of neuromuscular blockade is certainly minimized by sugammadex in combination with monitoring. However, the effect of sugammadex-aided recovery on patients’ satisfaction is unclear. This study compared the Quality of Recovery (QoR)-15 score, which is a patient-reported outcome, in patients undergoing laparoscopic cholecystectomy. Eighty patients were randomly assigned to the neostigmine or sugammadex groups. At the end of surgery, neostigmine or sugammadex was administered, and tracheal extubation was performed after confirmation of a train of four ratio ≥ 0.9. The QoR-15 questionnaire was administered at 1 day before surgery and on post-operative days (POD) 1 and 2. The primary outcome was the QoR-15 score on POD 1. The secondary outcomes were the QoR-15 score on POD 2, modified Aldrete score, length of post-anesthetic care unit stay, post-operative pain, administration of anti-emetics, urinary retention, and length of hospital stay. No significant differences were found in QoR-15 scores on POD 1 (94.4 vs. 95.5, p = 0.87) or 2 (116.3 vs. 122, p = 0.33). Secondary outcomes were also comparable, with the exception of urinary retention (15.8% neostigmine vs. 2.6% sugammadex, p = 0.04). This study demonstrated that the quality of recovery was comparable between the neostigmine and sugammadex groups when reversal and tracheal extubation were performed in accordance with the current guidelines.

CONSORT the effect of a bolus dose of dexmedetomidine on postoperative pain, agitation, and quality of recovery after laparoscopic cholecystectomy

BACKGROUND

The perioperative administration of dexmedetomidine may improve the quality of recovery (QoR) after major abdominal and spinal surgeries. We evaluated the effect of an intraoperative bolus of dexmedetomidine on postoperative pain, emergence agitation, and the QoR after laparoscopic cholecystectomy.

METHODS

Patients undergoing elective laparoscopic cholecystectomy were randomized to receive dexmedetomidine 0.5 μg/kg 5 minutes after anesthesia induction (dexmedetomidine group, n = 45) or normal saline (control group, n = 45). The primary outcome was the QoR at the first postoperative day using a 40-item scoring system (QoR-40). Secondary outcomes included intraoperative hemodynamic parameters, postoperative agitation, pain, and nausea and vomiting.

RESULTS

The heart rate and the mean blood pressure were significantly lower in the dexmedetomidine group than in the control group (P < .001 and .007, respectively). During extubation, emergence agitation was significantly lower in the dexmedetomidine group than in the control group (23% vs 64%, P < .001). The median pain scores in the post-anesthetic care unit were significantly lower in the dexmedetomidine group than in the control group (4 [2-7] vs 5 [4-7], P = .034). The incidence of postoperative agitation, pain, and nausea and vomiting was not different between the groups. On the first postoperative day, recovery profile was similar between the groups. However, the scores on the emotional state and physical comfort dimensions were significantly higher in the dexmedetomidine group than in the control group (P = .038 and .040, respectively).

CONCLUSIONS

A bolus dose of dexmedetomidine after anesthesia induction may improve intraoperative hemodynamics, emergence agitation, and immediate postoperative analgesia. However, it does not affect overall QoR-40 score after laparoscopic cholecystectomy.

Smartband Use During Enhanced Recovery After Surgery Facilitates Inpatient Recuperation Following Minimally Invasive Colorectal Surgery

Background: Enhanced recovery after surgery (ERAS) is valuable in perioperative care for its ability to improve short-term surgical outcomes and facilitate patient recuperation after major surgery. Early postoperative mobilization is a vital component of the integrated care pathway and is a factor strongly associated with successful outcomes. However, early mobilization still has various definitions and lacks specific strategies. Methods: Patients who underwent minimally invasive surgery for colorectal cancer followed our perioperative ERAS program, including mobilization from the first postoperative day. After perioperative care skills were improved in our well-established program, compliance, inpatient surgical outcomes, and complications associated with adding smartband use were evaluated and compared with the outcomes for standard protocol. Quality of recovery was evaluated using patient-rated QoR-40 questionnaires the day before surgery, on postoperative days 1 and 3, and on the day of discharge. Results: Smartband use after minimally invasive colorectal surgery failed to increase compliance with early mobilization or reduce the occurrence of postoperative complications significantly compared with standard ERAS protocol. However, when smartbands were utilized, quality of recovery was optimized and patients returned to their preoperative status earlier, at postoperative day 3. The length of hospital stay, as defined by discharge criteria, and hospital stay of patients without complications was reduced by 1.1 and 0.9 days, respectively (P = 0.009 and 0.049, respectively). Conclusions: Smartbands enable enhanced communication between patients and surgical teams and strengthen self-management in patients undergoing minimally invasive colorectal resection surgery. Accelerated recovery to preoperative functional status can be facilitated by integrating smartbands into the process of early mobilization during ERAS.

Comparison of the effects of intravenous propofol and inhalational desflurane on the quality of early recovery after hand-assisted laparoscopic donor nephrectomy: a prospective, randomised controlled trial

OBJECTIVES

We compared early recovery outcomes between living kidney donors who received total intravenous (IV) propofol versus inhalational desflurane during hand-assisted laparoscopic nephrectomy.

DESIGN

A single-centre, prospective randomised controlled trial.

SETTING

University hospital.

PARTICIPANTS

Study participants were enrolled between October 2019 and February 2020. A total of 80 living donors were randomly assigned to an intravenous propofol group (n=40) or a desflurane group (n=40).

INTERVENTION

Propofol group received intravenous propofol and desflurane group received desflurane, as a maintenance anaesthetic.

PRIMARY AND SECONDARY OUTCOME MEASURES

The quality of postoperative functional recovery was primarily assessed using the Korean version of the Quality of Recovery-40 (QoR-40K) questionnaire on postoperative day 1. Secondarily, ambulation, pain score, rescue analgesics, complications and total hospital stay were assessed postoperatively.

RESULTS

Our study population included 35 males and 45 females. The mean age was 46±13 years. The global QoR-40K score (161 (154-173) vs 152 (136-161) points, respectively, p=0.001) and all five subdimension scores (physical comfort, 49 (45-53) vs 45 (42-48) points, respectively, p=0.003; emotional state, 39 (37-41) vs 37 (33-41) points, respectively, p=0.005; psychological support, 30 (26-34) vs 28 (26-32) points, respectively, p=0.04; physical independence, 16 (11-18) vs 12 (8-14) points, respectively, p=0.004; and pain, 31 (28-33) vs 29 (25-31) points, respectively, p=0.021) were significantly higher in the intravenous propofol group than the desflurane group. The early ambulation success rate and numbers of early and total steps were higher, but the incidence of nausea/vomiting was lower, in the intravenous propofol group than the desflurane group. The total hospital stay after surgery was shorter in the intravenous propofol group than the desflurane group.

CONCLUSIONS

Intravenous propofol may enhance the quality of postoperative recovery in comparison to desflurane in living kidney donors.

Development and Validation of the Chinese Version of the Quality of Recovery-40 Questionnaire

PURPOSE

The present study aimed to develop the official Chinese version of the QoR-40 (QoR-40C) and to test its reliability, validity, and responsiveness.

PATIENTS AND METHODS

A systematic translation procedure was established and performed to develop the QoR-40C from the original English QoR-40 version. After the pilot study, 223 surgical patients were administered  the QoR-40C at four time points. The validity, reliability, and responsiveness were assessed to validate the QoR-40C.

RESULTS

The test-retest reliability of the QoR-40C in the morning and afternoon of the third day after surgery was 0.917 (P < 0.001). The split-half reliability for all domains was 0.938 in the morning of the third day after surgery. The median item-to-own dimension and total score of Cronbach's α for internal consistency of the QoR-40C at different assessment time points were more than 0.70. All the correlation coefficients between each subscale and the QoR-40 total score showed good correlation and were greater than those for other subscales in the morning of the third day after surgery. Furthermore, in the morning of the third day after surgery, the QoR-40C total score was moderately positively correlated with the SF-36 score (ρ = 0.575, P < 0.001), while the QoR-40C score was negatively correlated with the visual analogue scale (VAS) score (ρ = -0.299, P < 0.001). The factor loadings of each item were within the required range. A statistically significant difference was observed in the QoR-40C total scores before and after the surgery (P < 0.001) with the standardized responsive mean (SRM) of 0.51.

CONCLUSION

The QoR-40C showed good reliability, validity, and responsiveness and was appropriate to be used as a quality of life measurement questionnaire for patients after surgery in China.

Validity and reliability of the Korean version of the Quality of Recovery-15 questionnaire

Background

The quality of recovery-40 questionnaire (QoR-40) has been widely used to assess quality of recovery after surgery, but it is too lengthy for clinical use. The short form of QoR-40, QoR-15, has been validated in many languages; however, an official Korean version of the QoR-15 (QoR-15K) has not yet been established. This study aimed to develop and validate QoR-15K.

Methods

Based on the previously-validated Korean QoR-40, we selected 15 items; the QoR-15K was patterned on the original QoR-15. We analyzed 210 subjects who had been scheduled for elective surgery under general anesthesia. The patients completed the questionnaire before surgery and on postoperative days one and two. The validity, reliability, and responsiveness of the QoR-15K were evaluated.

Results

We obtained excellent convergent validity on visual analog scale for recovery (ρ = 0.882, P < 0.001). The duration of anesthesia, post-anesthesia care unit, and overall hospital stay with the QoR-15K showed a significant negative correlation (ρ = −0.183, −0.151, and −0.185, respectively). Cronbach’s α was 0.909. Cohen’s effect size and standardized response mean were 0.819 and 0.721. The recruitment and completion rate were 92.9% and 100%, respectively. We based the above calculations on the results obtained on the first day following surgery.

Conclusions

The validity and reliability of the QoR-15K are comparable to those of the English version. The QoR-15K would be a good instrument to assess the quality of recovery in Korean patients after surgery.

Comparison of the impact of propofol versus sevoflurane on early postoperative recovery in living donors after laparoscopic donor nephrectomy: a prospective randomized controlled study

Background

Enhancing postoperative recovery of the donor is important to encourage living kidney donation. We investigated the effects of anesthetic agents (intravenous [IV] propofol versus inhaled [IH] sevoflurane) on the quality of early recovery of healthy living kidney donors after hand-assisted laparoscopic nephrectomy (HALN) under analgesic intrathecal morphine injection.

Methods

This single-center, prospective randomized controlled study enrolled 80 living donors undergoing HALN from October 2019 to June 2020 at Seoul St. Mary’s Hospital. Donors were randomly assigned to the IV propofol group or IH sevoflurane group. To measure the quality of recovery, we used the Korean version of the Quality of Recovery-40 questionnaire (QoR-40 K) on postoperative day (POD) 1, and ambulation (success rate, number of footsteps) 6–12 h after surgery and on POD 1. The pain score for the wound site, IV opioid requirement, postoperative complications including incidences of nausea/vomiting, and length of in-hospital stay were also assessed.

Results

The global QoR-40 K score and all subscale scores (physical comfort, emotional state, physical independence, psychological support, and pain) were significantly higher in the IV propofol group than in the IH sevoflurane group. The numbers of footsteps at all time points were also higher in the IV propofol group. Donors in the IV propofol group had a lower incidence of nausea/vomiting, and a shorter hospitalization period.

Conclusions

Total IV anesthesia with propofol led to better early postoperative recovery than that associated with IH sevoflurane.

Validation and clinical utility of the Korean version of the Quality of Recovery-15 with enhanced recovery after surgery: a prospective observational cohort study

BACKGROUND

The 15-item Quality of Recovery (QoR-15) scale is a validated patient-reported outcome questionnaire that measures the quality of postoperative recovery. This study aimed to validate a translated Korean version of QoR-15 (QoR-15K) in a broad range of surgical patients.

METHODS

After Korean translation of the original English version of the QoR-15, we performed psychometric validation of the QoR-15K to evaluate the quality of recovery after surgery. The validity, reliability, responsiveness, and clinical feasibility of the QoR-15K were evaluated. A subgroup analysis in patients with video-assisted lung resection was performed.

RESULTS

Among 193 patients, 188 (97.4%) completed the QoR-15K after surgery. We found good convergent validity between the postoperative QoR-15K and the global QoR visual analogue scale (ρ=0.61, P<0.001). The negative correlation between the QoR-15K score and the extent of surgery (ρ=-0.33, P<0.001), the duration of surgery (ρ=-0.33, P<0.001), and the severity of postoperative pain (ρ=-0.40, P<0.001) supported construct validity. The postoperative QoR-15K showed good internal consistency (Cronbach α=0.90), split-half reliability (0.81), and test-retest reliability (0.95; 95% confidence interval [CI], 0.94-0.96). The QoR-15K score decreased from 140 (preoperative, inter-quartile range [IQR] 128-146) to 100 (postoperative day 1, IQR 75-122), median difference -36.5 (95% CI, -41 to -32.5; P<0.0001). The QoR-15K indicated excellent responsiveness with Cliff's effect size -0.78 (95% CI, -0.84 to -0.71). Subgroup analysis yielded similar results.

CONCLUSIONS

The QoR-15K is valid and has excellent reliability, a high degree of responsiveness, and clinical feasibility as a metric of quality of recovery in Korean surgical population.

Better timing of ultrasound-guided transversus abdominis plane block for early recovery after open inguinal herniorrhaphy: A prospective randomised controlled study

BACKGROUND

This study investigated the optimal timing of analgesic transversus abdominis plane (TAP) block in the operating room for better recovery quality using the Korean version of the Quality of Recovery-40 (QoR-40K) questionnaire in patients who had undergone open inguinal herniorrhaphy.

METHODS

This single-centre, prospective randomised controlled study included adult male patients who had an ASA physical status of I-II. A total of 80 patients were analysed. The patients were randomly assigned and classified into pre-incisional TAP (pre-TAP) block (n = 40) and post-incisional TAP (post-TAP) block (n = 40) groups. The quality of postoperative functional recovery and complications were compared between the two groups during 24 h postoperatively.

RESULTS

Preoperative findings of the two groups were comparable. The global QoR-40K score was higher in the pre-TAP group than in the post-TAP group. Among sub-dimensions, scores of physical comfort and pain were higher in the pre-TAP group than in the post-TAP group. In the post-anaesthesia care unit, the pre-TAP group showed lower pain scores than the post-TAP block group. There was no severe pain in the pre-TAP group, but two patients (5.0%) in the post-TAP block group suffered severe pain. The pre-TAP group required lower doses of IV rescue opioid in the PACU than the post-TAP group. All patients were discharged from hospital on postoperative day 1 without surgical complications.

CONCLUSIONS

The timing of analgesic TAP block may be of clinical importance to prevent postoperative pain and to improve the quality of early patient recovery following open inguinal herniorrhaphy.

Effect of Intravenous Lidocaine Infusion on Postoperative Early Recovery Quality in Upper Airway Surgery

OBJECTIVES/HYPOTHESIS

Systemic infusions of lidocaine have been widely used as perioperative analgesic adjuvants. The aim of this randomized, double-blinded, controlled trial was to investigate the effect of perioperative lidocaine infusion on postoperative early recovery quality in upper airway surgery.

STUDY DESIGN

Prospective, randomized, double-blinded, placebo-controlled trial.

METHODS

A total of 99 patients were randomly assigned to the lidocaine group (group L) or the control group (group C). The patients received 2 mg/kg lidocaine completed within 10 minutes before the induction of anesthesia followed by continuous infusions of 2 mg/kg/hr lidocaine (group L) or the same volume of 0.9% normal saline (group C) intravenously during anesthesia. The Quality of Recovery-40 (QoR-40) survey was administered on the preoperative day (Pre) and postoperative days 1 (POD1) and 2 (POD2). The primary endpoint was QoR-40 score on POD1 and POD2.

RESULTS

Compared with Pre, global QoR-40 scores on POD1 and POD2 were significantly lower (P < .05). Compared with group C, global QoR-40 scores were significantly higher in group L on POD1 and POD2 (P < .05). Among the five dimensions of QoR-40, the scores for physical comfort, emotional state, and pain were superior in group L compared to group C (P < .05). Compared with group C, the consumption of remifentanil and diclofenac as well as the incidence of postoperative nausea and vomiting (PONV) and postoperative 48-hour numeric rating scale (NRS) scores in group L were significantly lower (P < .05).

CONCLUSIONS

Systemic lidocaine infusion can improve QoR-40 scores in patients with upper airway surgery, reduce the dosage of intraoperative opioids, decrease the incidence of PONV and NRS scores 2 days after surgery, thus improving postoperative early recovery quality.

The effect of the type of anesthesia on the quality of postoperative recovery after orthopedic forearm surgery

Background

Although the quality of postoperative recovery may be affected by factors, there are few investigations whether the type of anesthesia also affects it. In this single-blinded, prospective, observational study, we compared the quality of postoperative recovery in patients undergoing orthopedic forearm surgery under general or regional anesthesia (brachial plexus block).

Methods

Ninety-seven subjects, aged 18–65 years and American Society of Anesthesiologists physical status I or II, undergoing orthopedic forearm surgery, were allocated to general or regional anesthesia group. The quality of postoperative recovery was assessed using a validated Korean version of Quality of Recovery-40 (QoR-40K) questionnaire. Patients were surveyed three times, the day before surgery (baseline) and 1st and 7th day after the surgery, and the scores of both groups were compared.

Results

We analyzed 47 and 50 patients in general and regional anesthesia, respectively. The global QoR-40K score and those of each of its five dimensions were not significantly different between the two groups at baseline, 1st and 7th day postoperatively. In two-way RM ANOVA, the global QoR-40K score at postoperative 1st day was significantly lower than that of baseline (P < 0.001) and postoperative 7th day (P < 0.001), respectively, in both general and regional anesthesia groups. However, there was no significant difference at each timepoint between the two groups.

Conclusions

The present study suggests that brachial plexus block with intravenous dexmedetomidine infusion does not improve the quality of postoperative recovery compared to sevoflurane inhalation anesthesia with remifentanil infusion in patients undergoing orthopedic forearm surgery.
