Conservative Surgical Management of a Pulmonary Hydatid Cyst in an Adolescent Having Extra-pulmonary Lesions by a Multi-disciplinary Approach.

Echinococcus granulosus causes hydatid cysts, a significant zoonotic and pulmonary parasitic disease that can mimic various pathologies and is often harder to manage than the disease itself. A hydatid cyst is considered a significant health problem in India, Iran, China, and Mediterranean countries, which lack satisfactory environmental health, preventive medicine, and veterinarian services. Echinococcosis continues to be a major community health burden in several countries, and in some terrains, it constitutes an emerging and re-emerging disease. Cystic echinococcosis is the most common human disease of this genus, and it accounts for a significant number of cases worldwide. Herein, a case involving an 11-year-old presenting with fever, dry cough, and right hypochondrial pain is presented, where imaging revealed a hydatid cyst in the lung. Surgical removal of the cyst was achieved through right posterolateral thoracotomy under one-lung ventilation and anesthesia using intubation with a double-lumen endotracheal tube (DLET or DLT), highlighting surgery as the primary treatment despite the lack of consensus on surgical methods. This case underscores the effectiveness of individualized, parenchyma-preserving surgery for even large, uncomplicated cysts, indicating a positive prognosis.

Single-point versus double-point injection technique of ultrasound-guided supraclavicular block: A randomized controlled study.

BACKGROUND AND AIMS: This study aims to compare the single-point injection and double-point injection technique of ultrasound-guided supraclavicular block with regard to the success rate, time taken to perform the procedure, onset and duration of sensory and motor block, and complications. MATERIAL AND METHODS: A total of 60 American Society of Anesthesiologists physical status I and II patients between 20 and 50 years of age, with body mass index ≤30 kg/m2 posted for forearm surgeries, with anticipated surgical duration more than 1 h were randomly divided into two groups: group S (single-point injection) and group D (double-point injection technique). After locating the brachial plexus with ultrasound, needle was inserted from lateral to medial direction to reach the plexus. In group D, 20 ml of inj. bupivacaine 0.5% was deposited as 10 ml each in superior (in the cluster) and inferior pocket (corner pocket) between the plexus and subclavian artery with the help of hydrodissection while in group S the total 20 ml was deposited in the superior (in the cluster) pocket. The onset of sensory and motor block was assessed using pin prick method and modified Bromage scale. Adequacy of block was ensured by assessing the ulnar, radial, and median nerve distribution. Procedural time was defined from the point of scanning the plexus till the drug was injected completely. Total sensory, motor duration, and complications if any were noted. RESULTS: Group D had higher success rate compared to group S (96.7 vs. 83.3%; P < 0.0001). The total procedural time was significantly more in group D compared to group S (14.6 ± 2.7 vs. 10.1 ± 1.7 min; P < 0.0001). The onset of sensory and motor block was faster and the duration of sensory and motor block was significantly longer in group D. CONCLUSION: The adequacy of block, sensory, and motor duration was significantly high in newer double-point injection technique. However, it requires longer procedural time compared to single-point injection technique.

Efficacy of intrathecal midazolam in potentiating the analgesic effect of intrathecal fentanyl in patients undergoing lower limb surgery.

INTRODUCTION: The intrathecal administration of combination of drugs has a synergistic effect on the subarachnoid block characteristics. This study was designed to study the efficacy of intrathecal midazolam in potentiating the analgesic duration of fentanyl along with prolonged sensorimotor blockade. MATERIALS AND METHODS: In a double-blind study design, 75 adult patients were randomly divided into three groups: Group B, 3 ml of 0.5% hyperbaric bupivacaine; Group BF, 3 ml of 0.5% hyperbaric bupivacaine + 25 mcg of fentanyl; and Group BFM, 3 ml of 0.5% hyperbaric bupivacaine + 25 mcg of fentanyl + 1 mg of midazolam. Postoperative analgesia was assessed using visual analog scale scores and onset and duration of sensory and the motor blockade was recorded. RESULTS: Mean duration of analgesia in Group B was 211.60 ± 16.12 min, in Group BF 420.80 ± 32.39 min and in Group BFM, it was 470.68 ± 37.51 min. There was statistically significant difference in duration of analgesia between Group B and BF (P = 0.000), between Group B and BFM (P = 0.000), and between Group BF and BFM (P = 0.000). Both the onset and duration of sensory and motor blockade was significantly prolonged in BFM group. CONCLUSION: Intrathecal midazolam potentiates the effect of intrathecal fentanyl in terms of prolonged duration of analgesia and prolonged motor and sensory block without any significant hemodynamic compromise.

Evaluation of ultrasound for central venous access in ICU by an in experienced trainee.

BACKGROUND AND AIMS: Central venous catheter placement is an important procedure for ICU (Intensive Care Unit) patients. We studied the usefulness of ultrasonography for placement of central venous catheter by in-experienced anesthetists. MATERIALS AND METHODS: A prospective observational study of 32 patients requiring central venous access (CVA) in surgical ICU (SICU). Data collected were patient's demographics, indication, type of catheter, success rate, attempts, complication rate and access time were recorded and compared with other studies. RESULT: The overall success rate was 89.5% in the IJV (Internal Jugular Vein) and 92.3% for SCV (Subclavian Vein) group. The success rates for insertion at first, second, and third attempt were 52.6%, 31.6%, and 5.2% for IJV and 46.2% and 53.8% for SCV. Average number of attempts made for IJV cannulation was 1.74 +/- 1.04 and 1.54 +/- 0.51 for SCV. The total time taken for IJV access was 858.78 +/- 381.9 sec, whereas in the SCV group, it was 984 +/- 328.98 seconds. In our study, overall rate of complication was 21.05% (4/19 patients) for IJV and 23.07% (3/13 patients) for SCV insertion. Incidence of various complications like arterial puncture, misplacement of CVC, hematoma, pneumothorax, and hemothorax were also noted. CONCLUSION: This study concludes that real time ultrasound guidance during IJV and SCV cannulation can achieve higher success rate, fewer complications, number of attempts, and failure rate among inexperienced anesthetists.
