Objective: Air-Q intubating laryngeal airway (ILA) is associated with a 58-77% success rate in blind intubation. The newer laryngeal mask airway (LMA) blockbuster is specially designed to facilitate easier endotracheal intubation and may have a higher success rate. The current study aimed to compare the success rate of endotracheal intubation using the Air-Q ILA and LMA blockbuster. Methods: After ethics committee approval and informed written consent, 140 adult patients with normal airways who were scheduled for elective surgery under general anaesthesia requiring endotracheal intubation were recruited for this randomized controlled trial. Blind endotracheal intubation was performed using the Air-Q ILA in group A and the LMA blockbuster in group B with special maneuvers and/or tubes in the second attempt. Fibreoptic bronchoscope (FOB) guidance was used in the third attempt if required. The primary outcome was the success rate of intubation without FOB assistance. The number of attempts for supraglottic airway (SGA) insertion, the time taken for SGA insertion, and the overall intubation time was also noted. Results: The success rate of intubation without FOB guidance was significantly higher in group B than in group A [91.4% vs 55.7%; relative risk (RR) 1.68; (95% confidence interval (CI) 1.34, 2.11); p<0.0001]. The number of attempts for SGA insertion was similar in groups A and group B [87% vs 90%; RR 1.03; (95% CI-0.92, 1.16); p=0.60]. The times for successful SGA insertion and endotracheal intubation were also similar between the groups. Conclusion: The LMA blockbuster offers a significantly higher success rate for endotracheal intubation without FOB guidance than the Air-Q ILA in adult patients with normal airways. However, an increased success rate was achieved with the use of a specially designed flexible endotracheal tube and maneuvers. [ABSTRACT FROM AUTHOR]

Background: The costoclavicular space serves as an alternative approach to the infraclavicular brachial plexus block, and numerous studies in adults have demonstrated promising outcomes for distal upper limb surgery. Blocking the brachial plexus at this level is potentially advantageous because the cords are relatively superficial, located in close proximity to each other and easily identified using ultrasound. Aims: This study aimed to assess the success rate and feasibility of costoclavicular block in children undergoing unilateral below elbow upper limb surgery. Methods: Thirty children aged 2–12 years scheduled for unilateral below elbow surgery under general anesthesia were included. Costoclavicular block was performed under ultrasound and nerve stimulator guidance with 0.5% ropivacaine, 0.5 mL/kg. Success was evaluated based on the absence of significant hemodynamic response to skin incision made 20 min after the block. The sono‐anatomy of costoclavicular space, ease of needling, complications, and the post‐operative pain scores were assessed. Results: The mean age and weight of the children were 6.5 ± 3.8 years and 19.7 ± 9.1 kg, respectively. The success rate of costoclavicular block in our cohort is 100%. Sonographic visualization was graded as excellent (Likert Scale 2) in 90% of cases. The plexus was located at a depth of 1.4 ± 0.3 cm from the skin, the lateral extent of cords from the artery was 0.8 ± 0.4 cm and they were observed inferior and lateral to the artery. The mean needling time was 3.6 ± 1.1 min. None of the children experienced complications such as vascular or pleural puncture, hematoma, Horner's syndrome or diaphragmatic palsy. Postoperative pain scores were low, and no rescue analgesia was required. Conclusions: In conclusion, the costoclavicular block exhibited a notably high success rate in pediatric population. This study substantiates that the three cords of the brachial plexus are consistently visible and superficial during ultrasound examination using this approach, confirming their separation from vascular structures and the reliable achievement of blockade without observed complications.

Background and Aims: Parental separation, fear, and exposure to the operating room environment lead to stress and anxiety in pediatric patients. This study aims to identify the research gaps in the effect of video distraction on pediatric patients of Indian origin. We hypothesized that video distraction along with parental presence would reduce preoperative anxiety in pediatric patients undergoing ophthalmic procedures under general anesthesia compared with parental presence alone. Material and Methods: In this prospective randomized trial, 145 patients aged 2-8 years, ASA I-II, with at least one functional eye undergoing elective ophthalmic daycare procedures were enrolled. They were randomly allocated to two Groups: Group V had distraction by watching a video/playing a video game together with parental presence, whereas control Group C had parental presence alone without any video distraction. The primary objective of the study was to compare preoperative anxiety using the Modified Yale Preoperative Anxiety score (mYPAS) and heart rate (HR), whereas the secondary objective was to compare child fear, emergence delirium, and parental satisfaction between the two groups. The three time points for intergroup comparisons were the preoperative holding area 10 min before induction (T0), transport of the child to the operating room (T1), and face mask introduction (T2). Results: There was a statistically significant difference between mYPAS score in groups V and C at all time points (P = 0.036, P = 0.0001, P = 0.0000), parental satisfaction score at all three time points (P = 0.0049, P = 0.0000, P = 0.0000), and Child Fear Score at T1 and T2 (P = 0.0001, P = 0.0001, respectively). However, there was no statistically significant difference in the emergence of delirium between the two groups. Conclusions: Video distraction together with parental presence has a promising role for implementation in hospitals with heavy workload settings where pharmacological intervention would not be feasible, to alleviate preoperative anxiety in children. However, preoperative anxiety may not translate into increased postoperative emergence delirium as was earlier believed. [ABSTRACT FROM AUTHOR]

Background and Aims: Comparison of analgesic efficacy of ultrasound-guided transmuscular quadratus lumborum block (QL-3) and erector spinae block (ESP) in children undergoing open pyeloplasty was done in this study. Material and Methods: This was a randomized, double-blinded, controlled study conducted in a tertiary care center, operating rooms, post-anesthesia care unit (PACU), and paediatric surgical ward. Sixty children of age 1-6 years, with American Society of Anesthesiologists (ASA) status I or II, undergoing elective open pyeloplasty were included in the study. Patients were randomized into two groups: group I (QL block-3) and group II (ESP). Both blocks were performed under USG guidance using 0.5 ml/kg of 0.25% ropivacaine after induction of general anesthesia. Postoperative Modified Objective Pain Score (MOPS), perioperative hemodynamic parameters, perioperative time for first rescue analgesia, total rescue analgesia, and incidence of complications were recorded. Statistical tests were applied as follows: (i) quantitative variables were compared using independent t-test/Mann-Whitney test (when the data sets were not normally distributed) between the two groups, and repeated measure analysis of variance (ANOVA)/Friedman test was used for comparison between different time intervals within the same group and (ii) qualitative variables were correlated using the Chi-square test/Fisher's exact test. A P value of <0.05 was considered statistically significant. Results: Pain was assessed using MOPS in the postoperative period at 0, 30 min, 1, 2, 4, 6, 12, and 24 h. Overall, the pain scores were low and showed a decreasing trend toward baseline as time progressed. Group I showed lower score, but was statistically significant only at the sixth hour. Highest mean score was 2.4 ± 2.01 in group I and 2.67 ± 2.32 in group II. Perioperative hemodynamic parameters were comparable. Total rescue analgesia during the perioperative period was not statistically significant (intraoperative P = 0.075 and postoperative P = 0.928). Also, 63.33% patients in group I and 63% patients in group II required rescue analgesia in the postoperative period and were comparable. Mean ± standard deviation (SD) for first rescue analgesia time was 6.32 ± 12.57 in group I and 16.67 ± 31.25 in group II, but not significant. The distribution in group II was skewed, hence the larger value for group II, but when compared to group I, this was statistically not significant. Conclusion: Both ultrasound-guided ESP block and QL block using 0.25% ropivacaine 0.5 ml/kg provided adequate analgesia during the first 24 h post-surgery in children undergoing open pyeloplasty. The fentanyl requirement during the first 24-h postoperative period was also decreased. [ABSTRACT FROM AUTHOR]

This article discusses the phenomenon of "happy hypoxemia" in COVID-19 patients, which refers to a condition where patients have low blood oxygen levels without experiencing significant respiratory distress. The study analyzed data from 450 patients admitted to a dedicated COVID unit and found a negative correlation between the oxygenation status and respiratory rate at admission. The study suggests that a lower baseline oxygenation ratio and the presence of self-reported shortness of breath were associated with a higher respiratory rate. The article emphasizes the importance of monitoring respiratory rate in COVID-19 patients as it can predict clinical deterioration and the need for mechanical ventilation.
