Comparison of the UEscope Video Laryngoscope with the Traditional Direct Laryngoscope in Neonates and Infants: A Randomized Clinical Trial.

The role of video laryngoscopy in adults is well established, but its role in children is still inconclusive. Previous studies on the UEscope in pediatric patients with difficult airways showed that it could reduce the time to intubation (TTI) compared to a conventional direct laryngoscope. The main objective of the current study was to investigate if the use of the UEscope could reduce the TTI in neonates and infants. Forty patients under 12 months old were recruited from a single tertiary hospital from March 2020 to September 2021 and were randomly assigned to the direct laryngoscope group (n = 19, neonates = 4, infants = 15) or UEscope group (n = 21, neonates = 6, infants = 15). Although the quality of glottic view was comparable in both groups, the TTI was significantly lower in the UEscope group in both the "intention-to-treat" (-19.34 s, 95% confidence interval = -28.82 to -1.75, p = 0.0144) and "as treated" (-11.24 s, 95% confidence interval: -21.73 to 0, p = 0.0488) analyses. The UEscope may be a better choice for tracheal intubation than conventional direct laryngoscope in neonates and infants.

Relationship between Preoperative Lower Back Pain and Severe Postoperative Pain after Gynecologic Laparoscopy: A Prospective Observational Study.

We hypothesized that preoperative lower back pain (LBP) may be associated with the severity of postoperative pain after gynecologic laparoscopy. This prospective observational study aimed to investigate the association between preoperative LBP and postoperative pain. We assessed the intensity of LBP before surgery and the postoperative pain after surgery. The abilities of preoperative LBP intensity, age, body mass index, and anesthetic duration time to predict moderate-to-severe postoperative pain were measured using receiver operating characteristic analysis. The data of 148 patients were analyzed. Only preoperative LBP intensity showed a significant association with moderate-to-severe postoperative pain (area under the curve, 0.71; 95% confidence interval, 0.63−0.79; p < 0.001). Preoperative LBP rated three on a numeric rating scale (NRS) had the highest combined sensitivity (75.3%) and specificity (58.3%). Patients with LBP above NRS 3 had more severe postoperative pain than those who did not (pain score 5.3 ± 2.2 vs. 3.9 ± 1.9, p < 0.001), leading to more opioid requirement in the recovery room (48.5% vs. 27.5%, p = 0.014). Preoperative LBP intensity is a useful factor for identifying patients at risk for pain after gynecologic laparoscopy.

Coprevalence of Presbycusis and Its Effect on Outcome of Voice Therapy in Patients With Presbyphonia.

OBJECTIVE: To identify the coprevalence of presbycusis and presbycusis and analyze the effect of presbycusis on compliance and result of voice therapy in presbycusis patients. METHODS: This cross-sectional, prospective cohort study initially screened patients aged ≥65 years who visited our hospital from February 2019 to January 2020. Unaided pure tone audiometry was performed in these subjects to determine the presence of presbycusis. Perceptual voice assessment by an examiner was conducted for screening of presbycusis, and its diagnosis was confirmed through the voice handicap index-10 (VHI-10) questionnaire and a laryngoscopic exam. Patients with presbycusis underwent voice therapy and were assessed for their compliance and outcomes of the treatment according to the coexistence of presbycusis. RESULTS: Among the 221 patients, presbycusis and presbycusis were diagnosed in 125 (56.6%) and 110 (49.8%) patients, respectively. The copresence of these two disorders were identified in 87 (39.4%) patients, and there was a significant correlation between presbycusis and presbycusis. The effects of voice therapy were examined in the consecutive 40 patients who were diagnosed with presbycusis. There were 21 patients without presbycusis and 19 patients with presbycusis. The average pretreatment voice handicap index-10 score was significantly higher in presbycusis patients; there was no significant difference in the incidence of dropout from voice therapy between the groups. The patients without presbycusis showed a significant improvement in the functional communication measurement (FCM) level and maximum phonation time (MPT) compared with those of patients with presbycusis after voice therapy. CONCLUSIONS: Presbyphonia and presbycusis coexisted in many elderly people. The improvement in the FCM level and MPT after voice therapy was relatively low if patients with presbycusis accompanied by presbycusis. The copresence of presbycusis did not significantly affect compliance with voice therapy in the patients.

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. TRIAL REGISTRATION: ClinicalTrials.gov NCT04409964 . Registered on 28 May 2020.

A Prospective Randomized Clinical Trial of Combination Therapy with Proton Pump Inhibitors and Mucolytics in Patients with Laryngopharyngeal Reflux.

OBJECTIVES: To identify whether combination therapy with mucolytics and proton pump inhibitors (PPIs) leads to faster and more effective symptomatic relief in patients with laryngopharyngeal reflux (LPR). METHODS: Patients diagnosed as LPR with a reflux symptom index (RSI) ≥ 13 and a reflux finding score (RFS) ≥ 7 were enrolled in this prospective study. Patients were randomly allocated to control (PPI only) or experimental (PPI + mucolytics) groups and changes in RSI and RFS values were assessed at 1- and 3-month follow-up. RESULTS: One hundred sixteen patients were randomly allocated into either the control group (n = 59) or the experimental group (n = 57). The RSI and RFS scores significantly decreased in both groups (all P < .001) after 1 month of treatment; however, there was no significant difference in RSI change between groups (P = .223). After 3 months of treatment, there remained no significant difference in RSI change between groups (P = .592). CONCLUSIONS: Combination therapy with mucolytics and PPI compared to PPI alone did not lead to faster or more effective symptomatic relief in LPR patients.
