Sugammadex for reversing neuromuscular blockages after lung surgery: A systematic review and meta-analysis.

BACKGROUND: This study determined whether sugammadex was associated with a lower risk of postoperative pulmonary complications and improved outcomes in lung surgeries. METHODS: A systematic literature search was conducted using PubMed, Embase, Web of Science, and the Cochrane Library from January 2000 to March 2022. The characteristics of lung surgeries using sugammadex treatment compared with control drugs and postoperative outcomes were retrieved. The primary outcome was estimated through a pooled odds ratio (OR) and its 95% confidence interval (CI) was identified using a random-effects model. RESULTS: From 465 citations, 7 studies with 453 patients receiving sugammadex and 452 patients receiving a control were included. The risk of postoperative pulmonary complication (PPCs) was lower in the sugammadex group than in the control group. Also, it showed that the effect of sugammadex on PPCs in the subgroup analysis was significantly assessed on the basis of atelectasis or non-atelectasis. Furthermore, subgroup analysis based on the relationship between high body mass index (BMI) and PPCs also showed that sugammadex had less occurrence in both the high BMI (defined as BMI ≥ 25) and low BMI groups. No difference in length of hospital stay (LOS) between the two groups was observed. CONCLUSION: This study observed that although reversing neuromuscular blockages with sugammadex in patients undergoing thoracic surgery recorded fewer PPCs and shorter extubation periods than conventional reversal agents, no difference in LOS, postanaesthesia care unit (PACU) stay length and chest tube insertion duration in both groups was observed.

Does surgical plethysmographic index-guided analgesia affect opioid requirement and extubation time? A systematic review and meta-analysis.

PURPOSE: This meta-analysis of all relevant clinical trials investigated surgical plethysmographic index (SPI)-guided analgesia's efficacy under general anesthesia for perioperative opioid requirement and emergence time after anesthesia. METHODS: PubMed, Embase, Web of Science, and Cochrane Library were searched up to January 2022 to identify clinical trials comparing SPI-guided and conventional clinical practice for patients who underwent general anesthesia. With the random-effects model, we compared intraoperative opioid consumption, emergence time, postoperative pain, analgesia requirement, and incidence of postoperative nausea and vomiting (PONV). RESULTS: Thirteen randomized controlled trials (RCTs) (n = 1314) met our selection criteria. The overall pooled effect sizes of all RCTs indicated that SPI-guided analgesia could not significantly reduce opioid consumption during general anesthesia. SPI-guided analgesia accompanied with hypnosis monitoring could decrease intraoperative opioid consumption (standardized mean difference [SMD] - 0.31, 95% confidence interval [CI] - 0.63 to 0.00) more effectively than SPI without hypnosis monitoring (SMD 1.03, 95% CI 0.53-1.53), showing a significant difference (p < 0.001). SPI-guided analgesia could significantly shorten the emergence time, whether assessed by extubation time (SMD - 0.36, 95% CI - 0.70 to - 0.03, p < 0.05, I2 = 67%) or eye-opening time (SMD - 0.40, 95% CI - 0.63 to - 0.18, p < 0.001, I2 = 54%). SPI-guided analgesia did not affect the incidence of PONV, postoperative pain, and analgesia management. CONCLUSION: SPI-guided analgesia under general anesthesia could enhance recovery after surgery without increasing the postoperative complication risk. However, it did not affect intraoperative opioid requirement. Notably, SPI-guided analgesia with hypnosis monitoring could effectively reduce intraoperative opioid requirement.

Music Intervention for Pain Control in the Pediatric Population: A Systematic Review and Meta-Analysis.

Music intervention (MI) has been applied as an effective adjunctive treatment for pain control in various clinical settings. However, no meta-analysis has yet been published on the analgesic effects of MI in infants and children. We performed a systematic review of PubMed, EMBASE, Web of Science, and Cochrane Library databases to identify randomized controlled trials (RCTs) with the keywords "pain" AND "music therapy" from inception to January 2022. Primary outcomes were pain intensity and vital signs. Standardized mean difference (SMD) values and the corresponding 95% confidence intervals (CIs) were computed using a random effect model. Subgroup analyses with age groups, types of pain, and music styles were conducted. A total of 38 RCTs involving 5601 participants met the selection criteria. MI significantly decreased the pain levels (SMD = -0.57, p < 0.001), both in the newborn group (p = 0.007) and in the infant/children group (p < 0.001). MI significantly reduced heart rate (SMD = -0.50, p < 0.001) and respiratory rate (SMD = -0.60, p = 0.002) and increased peripheral capillary oxygen saturation (SMD = 0.44, p < 0.001). In subgroup analyses of types of pain, MI had significant effects on prick pain (p = 0.003), chronic and procedural pain (p < 0.001), and postoperative pain (p = 0.018). As for music styles, significant analgesic effects were observed for classical music (p < 0.001), kids' music (p < 0.001), and pop music (p = 0.001), but not for world music (p = 0.196), special composition (p = 0.092), and multiple music combinations (p = 0.420). In conclusion, our analysis provides supportive evidence about the efficacy of MI, especially classical, kids', and pop music, in controlling prick, procedural, and postoperative pain in the pediatric population.

The Effect of Telehealth Services on Provider Productivity.

BACKGROUND: Telehealth services historically have played a small role in the provision of health care in the United States. However during the coronavirus disease 2019 (COVID-19) pandemic, public and private insurers rapidly expanded access to telehealth in order to reduce exposure and avoid transmission. It is unknown whether telehealth will become a more regular substitute for in-person care beyond the pandemic. OBJECTIVE: Our objective was to provide evidence on the value of telehealth by comparing the productivity of physicians and other specialized clinicians who provide telehealth with the productivity of those who do not. RESEARCH DESIGN: We conducted a retrospective data analysis of 17,705 unique providers in the areas of internal medicine, cardiology, dermatology, psychiatry, psychology, and optometry practicing in the US veterans affairs health care system during the period 2015 to 2018. For each year, we measured individual providers productivity by the total number of relative value units (RVUs) per full-time equivalent (FTE). We estimated the impact of providing telehealth on RVUs/FTE using fixed effects regression models estimated on a panel dataset of 58,873 provider-year observations and controlling for provider and patient characteristics. RESULTS: Overall provider productivity increased in veterans affairs over the period, particularly in cardiology and dermatology. Providers of telehealth had above average productivity by 124 RVUs/FTE, or ∼4% of average total provider productivity. For the highest quartile of telehealth providers, average productivity was 188 RVUs/FTE higher than productivity of other providers. CONCLUSION: Strategies that encourage long-term integration of telehealth into provider practices may contribute to overall health care value.

Epidural cyst with cauda equina syndrome after epidural anesthesia.

A 40-year-old woman without remarkable medical history received epidural anesthesia for uterine cervix conization. Six hours after the operation, cauda equina syndrome occurred. Magnetic resonance imaging of the spine revealed epidural fluid accumulation around L5, as well as L4/5 herniated intervertebral disc found incidentally. Surgical decompression was performed with H-reflex monitoring. Epidural injection could result in cystic accumulation complicated with cauda equina syndrome.

Evidence of increased DNA content of murine thymocytes caused by cocaine.

C57BL mice were injected intraperitoneally daily with 10 to 50 mg/kg of cocaine for five days. Four hours after the last injection, the thymuses were removed, and the effects on DNA and protein content of the surviving cells were measured. A dose-dependent increase in DNA content per cell, determined by UV spectrophotometric analysis, and a dose-dependent increase in protein content per cell, as measured using the Bio-Rad reagent, were observed. The increase in DNA content per cell was confirmed by H33258 staining of DNA as well as the diphenylamine assay. These changes were also observed when normal thymocytes were cultured with cocaine. Cell cycle analysis by flow cytometry of cocaine-treated cultures revealed the presence of aneuploid cells with increased DNA content. Fewer cells with aneuploidy were observed in experiments with significant apoptosis. Since both aneuploidy and enhanced apoptosis can be induced by cocaine and the amount of aneuploidy cells varies inversely with the degree of apoptosis, we hypothesize that cocaine causes DNA/chromosome damage, which eventually leads to cell death via the apoptosis pathway.
