An Inquiry on Airway Management by McCoy Blade with Elevated Tip and Miller Straight Blade with Paraglossal Technique: Relevance for Difficult Airway Management in Current Infectious Times.

Background: Modifications of curved and straight laryngoscope blades have been used for airway management since a long time. While McCoy blade with an elevated tip is commonly used to intubate patients with anticipated difficult airway, the Miller's straight blade is used for intubations in children and less commonly adults. In this study, we revisit the paraglossal technique of Miller's straight blade as a method to improve laryngeal view especially in difficult intubations. Aim: This study aimed to compare laryngoscopic view and ease of intubation (EOI) using McCoy blade elevated tip and Miller's straight blade paraglossal technique. Materials and Methods: A prospective single-blind study was conducted on 170 patients undergoing elective surgery under general anesthesia. They were randomly allotted to two groups. In Group A, laryngoscopy was performed by Miller's blade paraglossal approach, whereas in Group B, laryngoscopy was performed by McCoy blade with an elevated tip. Laryngeal view was graded using the modified Cormack-Lehane grading, and EOI was graded using EOI score. These were compared with preoperative intubation prediction score. Statistical analysis was done using "Medcalc" version 19.0.3. Numerical and categorical data were analyzed by Student's t-test and Chi-square test, respectively. A P < 0.05 was considered statistically significant. Results: The paraglossal approach with Miller's blade offered better laryngoscopic view as compared with McCoy blade with an elevated tip in normal (54.1% vs. 25.9%) and difficult airway (44.7% vs. 11.8%). Tracheal intubation was easier with McCoy blade with an elevated tip although the success rate of intubation improved with the assistance of a bougie with Miller's straight blade paraglossal approach. Conclusion: The laryngeal view was significantly better with the paraglossal approach of Miller's straight blade even in difficult airway. McCoy blade with an elevated tip was also found to be a useful tool to have in difficult airway, as EOI is significantly higher. The study also highlights the usefulness of adjuncts such as a gum elastic bougie while intubating.

Evaluation of postoperative pain in patients undergoing modified radical mastectomy with pectoralis or serratus-intercostal fascial plane blocks.

BACKGROUND: Regional nerve blocks are an integral part of multimodal analgesia and should be chosen based on their efficacy, convenience, and minimal side effects. Here, we compare the use of pectoral (PEC II) and serratus-intercostal fascial plane (SIFP) blocks in breast carcinoma cases undergoing modified radical mastectomy (MRM) in terms of the postoperative analgesic efficacy and shoulder mobility. METHODS: The primary outcome of this prospective controlled study was to compare the postoperative static and dynamic pain scores, and the secondary outcome was to assess the shoulder pain, range of shoulder joint motion, and hemodynamic parameters. Sixty patients were randomly allocated to three groups and given general anesthesia. All patients received paracetamol, diclofenac, and rescue doses of tramadol based on the Institute's Acute Pain Service (APS) policy. No block was performed in group C (control), whereas groups P and S received PEC II and SIFP blocks, respectively, before surgical incision. RESULTS: The groups were comparable in terms of age, weight, height, and body mass index distribution (P > 0.05). Dynamic pain relief was significantly better 12 and 24 h postoperatively in groups P (P = 0.034 and P = 0.04, respectively) and S (P = 0.01 and P = 0.02, respectively) compared to group C. Shoulder pain relief and shoulder mobility were better in group S, while the hemodynamic parameters were more stable in group P. CONCLUSIONS: Both SIFP and PEC blocks have comparable dynamic and static pain relief with better shoulder pain scores in patients receiving SIFP.

Movement disorders after stroke in adults: a review.

BACKGROUND: Movement disorders occur in association with stroke and may have important clinical implications. METHODS: We reviewed the medical literature regarding the clinical phenomenology, prevalence, localization and etiologic implications, and treatments for movement disorders occurring after stroke in adult patients. RESULTS: Movement disorders occur uncommonly after stroke and include both hyperkinetic and parkinsonian conditions. They can occur at the time of stroke or appear as a later manifestation. Stroke lesions are typically due to small vessel cerebrovascular disease in the middle or posterior cerebral artery territory, vessels supplying the basal ganglia. Hemorrhagic lesions are more likely to induce hyperkinetic movements. Movement disorders in the setting of stroke tend to resolve spontaneously over time. Medical and surgical therapies are available to treat the movement problems. DISCUSSION: Movement disorders after stroke can be helpful in localizing lesions after stroke, determining the etiology of stroke, may need to be a target for therapy and may importantly influence long term outcome.
