We aimed to compare BP values simultaneously recorded by invasive and noninvasive methods under general anesthesia (GA) during normotension, hypertension, and hypotension. Mean arterial pressure (MAP) values calculated by the automated technique were also compared to the values obtained using predefined formula. Material and Methods: An observational, prospective study was conducted in 250 adult patients undergoing elective surgeries under GA. Before induction, noninvasive blood pressure (NIBP) was measured in the arm in a supine position using an automated oscillometer. Radial artery in the opposite arm was cannulated. NIBP and arterial BP (ABP) were recorded simultaneously during normotension, hypotension, and hypertension. Results: During normotension and hypertension, systolic BP (SBP) measured by NIBP and ABP were comparable. Diastolic BP (DBP) and MAP during normotension were significantly higher with NIBP (73.65 ± 7.73 vs. 65.69 ± 8.39 and 87.79 ± 8.43 vs. 84.24 ± 8.82, respectively). During hypertension, DBP and MAP were significantly higher with NIBP (90.44 ± 11.61 vs. 78.59 ± 11.09 and 111.67 ± 10.43 vs. 105.63 ± 11.06, respectively).

Comparison of MAP measured by ABP and NIBP techniques with the MAP calculated using predefined formula in normotension showed significantly higher values with the automated technique. Conclusions: During normotension and hypertension, DBP and MAP showed significantly higher values with the NIBP technique compared to ABP, with comparable SBP values.

It also avoids flexion of the neck, lower back, and knee bending at the time of laryngoscopy and intubation. Material and Methods One hundred eighty patients were randomly allocated to three groups based on different table heights. The height of the table is kept at the mid-sternum level of an anesthesiologist in group 1, at the xiphoid process in group 2, and at the level of umbilicus in group 3. Laryngoscopic view with or without postural changes (exertion at wrist joint, flexion of the neck, lower back, or knee bending) was graded as per Cormack Lehane’s (CL) grading. The degree of discomfort experienced by the anesthesiologist during mask ventilation or tracheal intubation was graded subjectively (1 = no discomfort, 2 = mild discomfort, 3 = moderate discomfort, and 4 = severe discomfort) at different table heights. Postural changes required to obtain the best glottic view and quality of endotracheal (ET) intubation (intubation time and attempts required) were also noted. For analysis, quantitative variables were expressed as mean ± SD and compared using unpaired t or analysis of variance test. Qualitative variables were expressed as frequencies/percentages and compared using the Chi-square test. Results with P value <0.05 were considered significant statistically. Results Moderate discomfort (strain at wrist joint) during bag–mask ventilation was experienced by the anesthesiologist in a maximum number of patients in group 1 (81.7%). Significant improvement was seen in CL grade after the use of postural modifications in groups 1 and 2 ( P value ≤0.05). Greater postural modifications were required during ET intubation at lower table heights (group 3). Conclusions: It is advisable to adopt higher table positioning in relation to anesthesiologist performing the laryngoscopy for smooth and single-attempt ET intubation since the best laryngoscopic view and intubation with minimal postural modifications was seen at higher table heights (at the mid-sternum level of an anesthesiologist).","PeriodicalId":14946,"journal":{"name":"Journal of Anaesthesiology, Clinical Pharmacology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135943028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasound is being used for airway assessment, but there is still no established parameters or model to predict difficult laryngoscopy. This observational study was planned to determine the predictive ability of clinical and sonography-based airway assessment parameters for difficult laryngoscopy and intubation. Material and Methods: A total of 130 patients of 18–60 years of age undergoing elective intubation were included. The distribution of Cormack–Lehane (CL) grade and intubation difficulty scale (IDS) was correlated with the clinical and sonographic screening parameters for difficult airways. Results The prevalence of difficult laryngoscopy and difficult intubation in our study was 17.6% and 11.5%, respectively. Mallampati grade (MMG), upper lip bite test (ULBT), neck circumference, hyomental distance ratio (HMDR), tongue thickness (TT), skin to epiglottis/epiglottis to vocal cord distance (SED/E-VC), and mandibular condylar mobility (MCM) had significant association with the difficult laryngoscopy and MMG, neck circumference, SED, SED/E-VC; MCM had significant association with the difficult intubation. The combination of these predictors showed better diagnostic ability for difficult airways. Model 1 based on ultrasound parameters showed an area under the curve (AUC) of 0.848 (CI- 0.748-0.947, P value < 0.0001) and model 2 based on combined clinical and ultrasound parameters showed an AUC of 0.755 (95% CI- 0.631-0.879, P value < 0.0001).

Modified radical mastectomy (MRM) is a commonly performed surgery for breast cancer. The objective of the study is to compare the efficacy of ESPB and TPVB in providing postoperative pain relief after MRM. Material and Methods: This is a prospective randomized study conducted in a tertiary care teaching hospital. Sixty ASA I–III adult patients (age >18 years) scheduled to undergo elective unilateral MRM for breast cancer were enrolled in the study. Ultrasound-guided ESPB or TPVB with 0.25% bupivacaine was performed preoperatively on the patients randomized into two groups, namely, the ESPB and TPVB groups. All patients received patient-controlled analgesia for postoperative pain relief. Morphine consumption and Visual Analog Score (VAS) for pain were recorded at 3, 6, 12, and 24 h postoperatively. Results: Primarily, the mean postoperative VAS scores between the two groups at 3, 6, 12, and 24 h showed no statistical significance and were comparable when matched at different time points. However, 24-h morphine consumption was significantly more in the ESPB group ( P = 0.035). Duration of block performance also showed a significant difference, with ESPB taking less time to perform ( P < 0.001). The mean age and body mass index (BMI) of patients and length of hospital stay in both the groups were similar.
