Efficacy of dexmedetomidine as an adjunct to ropivacaine in bilateral dual-transversus abdominis plane blocks in patients with ovarian cancer who underwent cytoreductive surgery

Objective We sought to evaluate the postoperative control of pain and recovery in patients with ovarian cancer who underwent cytoreductive surgery by adding dexmedetomidine to ropivacaine in bilateral dual-transversus abdominis plane (Bd-TAP) blocks. Methods We enrolled 90 patients with an American Society of Anesthesiologists physical status I to III undergoing open abdominal cytoreductive surgery in this study. Patients were randomized and assigned into three groups (TAP-R, TAP-DR, or CON) of 30 participants each. All of the patients received standardized general anesthesia, and postoperative Bd-TAP blocks were performed. The TAP-R, TAP-DR, and CON groups received Bd-TAP blocks with 0.3% ropivacaine, 0.3% ropivacaine and 0.5 μg/kg of dexmedetomidine, and 0.9% normal saline, respectively. All of the patients received patient-controlled analgesia (PCA) (formula, 100 μg of sufentanil and 16 mg of ondansetron diluted with normal saline to 100 mL). Flurbiprofen axetil was used as a rescue drug if the visual analog scale (VAS) score was more than four points. The first request time for PCA bolus; the VAS scores at 0, 6, 12, 24, and 48 h after operation; and the cumulative sufentanil consumption within 24 and 48 h, respectively, were compared. Pulmonary function was evaluated preoperatively and at 24 h after the operation. The use of the rescue drug was recorded. Postoperative functional recovery, including time to stand, time to walk, time to return of bowel function, time to readiness for discharge, and postoperative complications, were recorded. Results Median values of the first request time for PCA of the TAP-R group was significantly prolonged compared to that of the CON group (median [interquartile range], 7.3 [6.5–8.0] hours vs. 3.0 [2.3–3.5] hours) (P < .001), while the TAP-DR group has the longest request time among the three groups (median [interquartile range], 13.5 [12.4–14.5] hours) (P < .001). The VAS scores at rest and upon coughing of the TAP-R group in the first 12 h were significantly lower than those of the CON group (P < 0.05), but showed no significant difference compared to those of the TAP-DR group. The VAS scores at rest and upon coughing were lower in the TAP-DR group at each time point compared to those of the CON group (P < .05). The cumulative sufentanil consumption in the TAP-DR group was significantly lower at 48 h (P = .04) after surgery than in the CON group, while there was no significant difference compared to that in the TAP-R group (P > .05). Less rescue analgesic was required by patients in the TAP-DR group than in the CON group (P < .05). Postoperative mean measured forced expiratory volume in 1 s (FEV1) and FEV1/forced vital capacity values in the TAP-DR group were significantly higher than those of the CON group (P = .009), while there was no significant difference compared to those of the TAP-R group (P = .10). There was no significantly difference in postoperative functional recovery between TAP-DR and CON group (P > 0.05). Conclusion TAP blocks can provide effective pain relief up to 12 h postoperatively without a significant improvement in postoperative pulmonary function. The addition of dexmedetomidine to ropivacaine for Bd-TAP block prolonged the first bolus time of PCA when compared to that in the TAP-R group and decreased sufentanil consumption and the need of rescue analgesia relative to in the CON group at 48 h postoperative. The procedure provided better postoperative analgesia and improved postoperative pulmonary function relative to the CON group. Our results indicate that dexmedetomidine as an adjuvant of Bd-TAP can provide effective pain relief up to 48 h.

Utility of Visual Analog Scale of Subdomain Scores of the 22-Item Sinonasal Outcome Test in Chronic Rhinosinusitis

The burden of chronic rhinosinusitis (CRS) symptomatology is frequently measured with the 22-item Sinonasal Outcome Test (SNOT-22). In some situations, such as when there is need for frequent sampling, a full SNOT-22 may be impractical, and an abbreviated measure may be useful. Herein, we study 4 questions reflecting the 4 SNOT-22 subdomains as accurate reflections of SNOT-22 content. In total, 250 patients with CRS completed a SNOT-22 and answered 4 questions about their total nasal symptoms, poor sleep quality, ear/facial pain, and mood (reflecting SNOT-22 subdomains) using visual analog scales (VASs). The 4 SNOT-22 subdomain VAS scores each correlated strongly with the corresponding SNOT-22 subdomain scores. The sum of the 4 subdomain question VAS scores was highly correlated with the total SNOT-22 score ( r = 0.77, P < .001). This preliminary study suggests information from the SNOT-22 may be ascertained through 4 questions reflecting the 4 SNOT-22 subdomains, although further validation is needed.

The Effect of Improving Preoperative Sleep Quality on Perioperative Pain by Zolpidem in Patients Undergoing Laparoscopic Colorectal Surgery: A Prospective, Randomized Study

Background and Objectives. Opioids are essential in pain management after laparoscopic colorectal surgery while large dose may induce constipation and pneumonia. Ample evidence has demonstrated that postoperative analgesia can improve sleep quality. But the effects of improvement in sleep quality on postoperative pain have yet to be determined. The aim of this study was to investigate the effect of improving preoperative sleep quality by zolpidem on intraoperative analgesia and postoperative pain. Methods. A prospective, randomized study was conducted with 88 patients undergoing laparoscopic colorectal surgery. The experimental group (S group, n = 44) was given 10 mg of zolpidem tartrate one night before the surgical procedure, while no medication was given to the control group (C group, n = 44). The primary outcome was the intraoperative remifentanil consumption. Sufentanil consumption, average patient-controlled analgesia (PCA) effective press times, the visual analog scale (VAS) scores, and incidences of postoperative nausea and vomiting (PONV) were recorded at 6 h (T1), 12 h (T2), and 24 h (T3) postoperatively. Results. The intraoperative remifentanil consumption was significantly lower in the S group than that in the C group ( p < 0.01 ). Sufentanil consumption at 6 h and 12 h postoperatively was significantly lower in the S group than that in the C group ( p < 0.05 ); average PCA effective press times and VAS scores, at 6 h and 12 h postoperatively, were significantly lower in the S group than those in the C group ( p < 0.01 ); differences between groups 24 h postoperatively were not significant. No significant between-group difference was noted in the incidence of nausea and vomiting. Conclusion. Improving patients’ sleep quality the night before surgical procedure by zolpidem can decrease the usage of intraoperative analgesics and reduce postoperative pain.

Performance of the EQ-5D-Y Interviewer Administered Version in Young Children

(1) Background: An estimated 78% of South African children aged 9–10 years have not mastered basic reading, therefore potentially excluding them from self-reporting on health-related outcome measures. Thus, the aim of this study was to compare the performance of the EQ-5D-Y-3L self-complete to the newly developed interviewer-administered version in children 8–10 years. (2) Methods: Children (n = 207) with chronic respiratory illnesses, functional disabilities, orthopaedic conditions and from the general population completed the EQ-5D-Y-3L self-complete and interviewer-administered versions, Moods and Feelings Questionnaire (MFQ) and Faces Pain Scale-Revised (FPS-R). A functional independence measure (WeeFIM) was completed by the researcher. (3) Results: The 8-year-olds had significantly higher missing responses (x2 = 14.23, p < 0.001) on the self-complete version. Known-group and concurrent validity were comparable across dimensions, utility and VAS scores for the two versions. The dimensions showed low to moderate convergent validity with similar items on the MFQ, FPS-R and WeeFIM with significantly higher correlations between the interviewer-administered dimensions of Mobility and WeeFIM mobility total (z = 1.91, p = 0.028) and Looking After Myself and WeeFIM self-care total (z = 3.24, p = 0.001). Children preferred the interviewer-administered version (60%) (x2 = 21.87, p < 0.001) with 22% of the reasons attributed to literacy level. (4) Conclusions: The EQ-5D-Y-3L interviewer-administered version is valid and reliable in children aged 8–10 years. The results were comparable to the self-complete version indicating that versions can be used interchangeably.

Percutaneous Vertebroplasty: Efficacy of Unipedicular Vertebroplasty as Compared to Bipedicular Vertebroplasty

Introduction Percutaneous vertebroplasty has been used for treatment of intractable painful fractures of vertebral bodies. With the help of refined procedures and standard techniques, the interventional radiologist can now offer help to orthopedics and neurosurgeons in these cases, which include treatment of vertebral compression fracture. Vertebroplasty is aimed at reducing the pain induced by collapse. Vertebroplasty is the standard mode of treatment for vertebral collapse, and in our study, bipedicular vertebroplasty was compared with unipedicular approach as bipedicular vertebroplasty is the routinely used approach. Aim To compare efficacy of unipedicular percutaneous vertebroplasty with that of bipedicular percutaneous vertebroplasty. Material and Methods A total of 52 vertebroplasties were done over a period of 2 years. Out of 52 patients, 28 patients underwent unipedicular vertebroplasty and 24 patients underwent bipedicular vertebroplasty. Visual analogue scale (VAS) scores were used to assess the pain prior to vertebroplasty and after vertebroplasty. Efficacy of the two procedures were assessed by comparing VAS scores. Results There was no statistically significant difference observed in the preprocedure and postprocedure VAS scores (p-value < 0.0001, < 0.0001, respectively). The mean procedure time was lesser in unipedicular vertebroplasty (41.9 ± 3.90) than bipedicular vertebroplasty (54.5 ± 3.4). Conclusion Unipedicular vertebroplasty is as effective as bipedicular vertebroplasty, as there is insignificant difference in postprocedure VAS scores between the unipedicular and bipedicular vertebroplasty.

Association of Acute Postoperative Pain and Cigarette Smoking With Cerebrospinal Fluid Levels of Beta-Endorphin and Substance P

Objectives: Cigarette smoking is associated with postoperative pain perception, which might be mediated by beta-endorphin and substance P. These effects on postoperative pain perception have never been investigated in human cerebrospinal fluid (CSF), which reflects biochemical alterations in the brain. Therefore, we investigated the associations among cigarette smoking, postoperative pain, and levels of beta-endorphin and substance P in human CSF.Methods: We recruited 160 Chinese men (80 active smokers and 80 nonsmokers) who underwent lumbar puncture before anterior cruciate ligament reconstruction, and 5-ml CSF samples were collected. Pain visual analog scale (VAS) scores, post-anesthetic recovery duration (PARD), and smoking variables were obtained. CSF levels of beta-endorphin and substance P were measured.Results: Compared to non-smokers, active smokers had significantly higher pain VAS (2.40 ± 0.67 vs. 1.70 ± 0.86, p &lt; 0.001) and PARD scores (9.13 ± 2.11 vs. 7.27 ± 1.35, p = 0.001), lower CSF beta-endorphin (33.76 ± 1.77 vs. 35.66 ± 2.20, p = 0.001) and higher CSF substance P (2,124.46 ± 217.34 vs. 1,817.65 ± 302.14, p &lt; 0.001) levels. Pain VAS scores correlated with PARD in active smokers (r = 0.443, p = 0.001).Conclusions: Cigarette smoking is associated with increased postoperative pain intensity, shown by delayed pain perception, higher pain VAS scores, and lower beta-endorphin and higher substance P levels in the CSF of active smokers. The more extended postoperative pain perception is delayed, the more pain intensity increases.

Efficacy of Curcuminoids in managing postoperative pain after total laparoscopic hysterectomy: A randomized controlled, open-label trial.

Background and aims: Curcuminoids, which are substances extracted from turmeric (Curcuma longa), have anti-inflammatory and analgesic effects and a good safety profile. This study aimed to evaluate the clinical efficacy of curcuminoid extracts on reducing pain among patients who underwent laparoscopic hysterectomy. Experimental procedure: From November 2016 to December 2017, 98 participants were included in this clinical trial, and they were randomly assigned to the experimental and control arms according to blocks of four. The intraoperative findings did not significantly differ between the two groups. The experimental group received one tablet of curcuminoid extract 250 mg four times a day on postoperative days 1–3. Pain was evaluated at 24 and 72 h postoperatively using a 10-point visual analog scale (VAS). Results and conclusion: The mean visual analog scale (VAS) scores at 24 h after surgery were 4.9 in the experimental group and 4.3 in the control group. Hence, the results did not significantly differ (p = 0.129). The mean VAS scores at 72 h after surgery were 1.8 in the experimental group and 2.8 in the control group (p = 0.001). The side effects in both groups were similar. Hence, curcuminoids can be an effective supplement for reducing pain after laparoscopic hysterectomy. The conclusion from this study is, that curcuminoids may be an effective supplement to reduce postoperative pain following laparoscopic hysterectomy.

Clinical results following robotic navigation guidance for sacroiliac joint fusion in 36 patients

OBJECTIVE In this study, the authors aimed to describe a new technique of sacroiliac joint (SIJ) fusion using a robotic navigation guidance system and to document clinical results with patient-reported visual analog scale (VAS) scores. METHODS Patients diagnosed with SIJ dysfunction were surgically treated using 2 hydroxyapatite (HA)–coated, threaded screws with the aid of the robotic navigation system. In a total of 36 patients, 51 SIJs were fused during the study period. Patients’ VAS scores were used to determine clinical improvement in pain. Postoperative imaging at routine intervals during the follow-up period was also performed for assessment of radiological fusion. In addition, complication events were recorded, including reoperations. RESULTS All 36 patients had successful fusion evidenced by both CT and clinical assessment at the final follow-up. Two patients underwent reoperation because of screw loosening. The mean preoperative VAS score was 7.2 ± 1.1, and the mean 12-month postoperative VAS score was 1.6 ± 1.46. This difference was statistically significant (p < 0.05) and demonstrated a substantial clinical improvement in pain. CONCLUSIONS Robotic navigation–assisted SIJ fusion using 2 HA-coated, threaded screws placed across the joint was an acceptable technique that demonstrated reliable clinical results with a significant improvement in patient-reported VAS pain scores.

Longitudinal study of patients’ health-related quality of life using EQ-5D-3L in 11 Swedish National Quality Registers

ObjectiveTo compare problems reported in the five EQ-5D-3L dimensions and EQ VAS scores at baseline and at 1-year follow-up among different patient groups and specific diagnoses in 11 National Quality Registers (NQRs) and to compare these with the general population.DesignLongitudinal, descriptive study.Participants2 66 241 patients from 11 NQRs and 49 169 participants from the general population were included in the study.Primary and secondary outcome measuresProportions of problems reported in the five EQ-5D-3L dimensions, EQ VAS scores of participants’ own health and proportions of participants and mean/median EQ VAS score in the Paretian Classification of Health Change (PCHC) categories.ResultsIn most of the included registers, and the general population, problems with pain/discomfort were the most frequently reported at baseline and at 1-year follow-up. Mean EQ VAS score (SD) ranged from 45.2 (22.4) among disc hernia patients to 88.1 (15.3) in wrist and hand fracture patients at baseline. They ranged from 48.9 (20.9) in pulmonary fibrosis patients to 83.3 (17.4) in wrist and hand fracture patients at follow-up. The improved category of PCHC, improvement in at least one dimension without deterioration in any other, accounted for the highest proportion in several diagnoses, corresponding with highest improvement in mean EQ VAS score.ConclusionsThe study documented self-reported health of several different patient groups using the EQ-5D-3L in comparing with the general population. This demonstrated the important role of patient-reported outcomes in routine clinical care, to assess and follow-up health status and progress within different groups of patients. The EQ-5D-3L descriptive system and EQ VAS have an important role in providing a ‘common denominator’, allowing comparisons across NQRs and specific diagnoses.Trial registration numberClinicalTrials.gov (NCT04359628).

Preoperative T1 magnetic resonance imaging changes carry a poor postoperative prognosis in cervical myelopathy: A retrospective study of 182 patients

Background: T2 scans are widely used to determine the prognosis for patients undergoing surgery for cervical myelopathy. In this study, we determined whether T1 MR changes in addition to T2 MR changes could have prognostic importance. Methods: This retrospective analysis involved 182 patients undergoing surgery for cervical myelopathy (2017–2020). There were 110 patients in Group 1 (only T2 MR changes) and 72 in Group 2 (both T1 and T2 MR changes). In addition, demographic, visual analog score (VAS), modified Japanese Orthopaedic Association (mJOA) scores, and operative details were recorded at 1 month, 3 months, 6 months, and 1 year postoperatively. Results: Notably, VAS scores were comparable at each point in time and were significantly better than the preoperative scores at 1 year postoperatively. Although mJOA scores were comparable at 1 month in both groups, they were better thereafter for Group 1 patients. Conclusion: The presence of T1 changes on the preoperative magnetic resonance imaging represented a poor prognostic indicator for the postoperative outcome compared to the presence of T2 changes alone.
