Author(s): Kinjal Chaudhary [1]; Neeta Bose [2]; Dhara Tanna (corresponding author) [1]; Anup Chandnani [1] INTRODUCTION Severe pain associated with proximal femur fracture makes spinal anaesthesia in a sitting position [...], Background and Aims: Femoral nerve block is a widely used analgesia technique for positioning before spinal anaesthesia for proximal femur fracture surgeries. Pericapsular nerve group (PENG) block is a newer technique with motor-sparing characteristics. We compared the analgesic efficacy of these blocks for patient positioning for spinal anaesthesia. Methods: In this study, 60 patients were randomised to either the PENG group (n = 30) or the femoral group (n = 30). After performing the block, the pain was assessed every 10 min using a visual analogue scale (VAS) score for 30 min. The primary objective was the median [interquartile range (IQR)] reduction in pain (dynamic VAS with 15-degree passive limb elevation) at 30 min. Secondary objectives were ease of spinal position score (EOSP), angle obtained during positioning, duration of postoperative analgesia and quadriceps weakness. Results: The demographics were comparable in both groups. After 30 min, the median (IQR) VAS was 6 (5-7) in the PENG group and 5 (5-6) in the femoral group (P = 0.004). Secondary outcomes such as EOSP score and angle obtained by patients were comparable. In the postoperative period, patients had significantly lower pain in the PENG group compared to the femoral group. The duration of analgesia was prolonged with PENG block. Quadriceps weakness was significantly low with PENG block (P < 0.001). Conclusion: PENG block provides better analgesia than a femoral block before spinal anaesthesia for proximal femur fracture surgery. The postoperative duration of analgesia was also longer.

Author(s): Shaji A. Manuel [1]; Dhara B. Tanna (corresponding author) [1]; Heena K. Patel [1]; Neeta Bose [1] INTRODUCTION Cardiopulmonary resuscitation (CPR) is a necessary life-saving skill for all medical [...], Background and Aims: Medical professionals must be able to perform life-saving skills like cardiopulmonary resuscitation (CPR) during emergency situations, even outside the hospital. The foundation course for the first-year medical students includes first aid and CPR training. This quasi-experimental study was conducted to assess the effectiveness of basic cardiac life support (BCLS) training based on Indian guidelines, on the self-confidence and knowledge regarding CPR of first-year medical students. Methods: This study was conducted during the foundation course for first-year medical students. The training included a common lecture for all the students followed by a 4 day long practical training in groups of 45-46 students, each day. BCLS training was carried out in three skill stations - airway, chest compressions and full sequence CPR. Students&apos; skills were recorded real time on a skill assessment manikin after completion of the hands-on training. The students were asked to fill a questionnaire regarding knowledge and self-confidence, before and after the training. The outcome measures were the difference in knowledge and self-confidence with regard to CPR before and after the training. Results: Out of the 199 students, 181 were included in the analysis. There was significant improvement in the knowledge score (pre-test - 1.46 versus post-test - 8.27, P < 0.001). The overall confidence regarding first aid skills, BCLS knowledge and self-confidence for performing BCLS improved significantly. Conclusion: There is improvement in knowledge and self-confidence regarding CPR and the students develop an acceptable level of skills after the training.

Background: Ultrasound (USG)-guided interscalene block (ISB) provides excellent anesthesia and analgesia for humerus surgery. Various adjuvants have been used to improve the quality of block and duration of analgesia. Aim: The aim of the study was to compare the efficacy of dexmedetomidine (DXM) and dexamethasone (DXA) as an adjuvant to 0.75% ropivacaine for interscalene brachial plexus block among patients undergoing humerus surgery. Settings and Design: The study design was a prospective randomized comparative study at a tertiary care teaching hospital. Materials and Methods: After ethical approval and CTRI registration, 52 patients of 18-60 years of age, American Society of Anesthesiology Grade I-II, scheduled for proximal and mid-shaft humerus surgery were randomly allocated in Groups A and B. Group A (n=26) received Ropivacaine 0.75% (20 ml) along with DXM 0.5 μg/ Kg and 2 ml saline (total 22 ml) and Group B (n=26) received Ropivacaine 075% along with DXA 8 mg (total 22 ml). ISB was performed with an in-plane technique using a linear probe. Duration of analgesia, block characteristics (onset, complete sensory, and motor block), and complications were recorded and compared for 24 h. Statistical Analysis: Data were statistically analyzed with Social Science Statistics. Student's unpaired t-test and Chi-square tests were used, and all statistical tests were examined with P ≤ 0.05 level of significance. Results: The duration of analgesia in Group B was significantly longer than Group A (13 h 12 min ± 2 h 33 min-8 h 48 min ± 1 h 52 min, P < 0.00001). The groups were comparable regarding block characteristics, baseline demographics, and intraoperative hemodynamic parameters. Conclusion: DXA as an adjuvant to ropivacaine provides analgesia for longer duration compared to DXM in USG-guided ISB. [ABSTRACT FROM AUTHOR]

Abstract Background. Tubercular brain abscess (TBA) is a rare manifestation of CNS tuberculosis. It is characterised by an encapsulated collection of pus, containing viable tubercular bacilli without evidence of tubercular granuloma. Presentation and history. Patients may present with features of raised intracranial pressure and focal neurological deficit commensurate with the site of the abscess. A history of pulmonary tuberculosis may be present, as documented in one of our six cases; three of our six children developed TBA despite 3-weeks to 12-month courses of antitubercular chemotherapy prescribed for post-TBM hydrocephalus. Diagnosis. Contrast CT head, MRI, MR spectroscopy is helpful in making the diagnosis and planning the treatment. TBA may be unilocular or multilocular on contrast CT scan. A relatively long clinical history and an enhancing capsule with thick wall are suggestive of TBA. Pyogenic abscess, however, has a thin rim on contrast CT. The capsule of TBA is formed of vascular granulation tissue containing acute and chronic inflammatory cells, particularly polymorphs. Proof of tubercular origin must be demonstrated either by presence of acid fast bacilli in culture or staining of pus or wall. Treatment. Treatment options include simple puncture, continuous drainage, fractional drainage, repeated aspiration through a burr hole, stereotactic aspiration and total excision of the abscess. Total excision usually becomes necessary in multilocular noncommunicating and thick-walled abscesses. Antitubercular therapy is the mainstay of management. The development of fulminant tubercular meningitis is sometimes problematic following surgical excision of TBA, as seen in one of our four operated cases. Mortality is reported to be high despite progress in treatment, while five of the six children treated by us responded well to the treatment. [ABSTRACT FROM AUTHOR]

Background: There is a dearth of studies on the clinical profile and therapeutic aspects of critically ill obstetric patients from rural areas, especially those requiring tertiary care support and ventilator therapy., Methods: We retrospectively analysed the aetiological, clinical, interventional and outcome-related factors of obstetric patients requiring mechanical ventilation in western India. We analysed factors that influence seeking of antenatal care, pregnancy and its complications, severity assessment score, indications and initiation of mechanical ventilation, multiorgan failure and their correlation with maternal mortality., Results: Of the 6708 obstetric admissions studied, 1112 were of critically ill (16.5%) patients and 200 (17%) of these required mechanical ventilation. Over three-fourths (77%) of patients were from rural areas, 83.5% were referred and 97% had inadequate antenatal care. Severe pregnancy-induced hypertension/eclampsia, massive haemorrhage and sepsis were the common obstetric complications. Pulmonary oedema (32.5%), acute respiratory distress syndrome (ARDS, 14%) and acute lung injury (22.5%) were the three most common indications for mechanical ventilation. In 26% of patients, mechanical ventilation was initiated early based on a worsening cardiorespiratory profile. A sequential organ failure assessment score of >5 on admission and delay in treatment resulted in multi-organ failure and worsening outcome. The maternal mortality ratio was 32.5%, incidence of multi-organ dysfunction syndrome was 71%, and pregnancy loss was 43.5%. The odds ratio for maternal mortality in patients ventilated early was 0.39 as against 5 in those with ARDS., Conclusions: Inadequate antenatal care, delayed referral practices, pregnancy-induced hypertension, obstetric haemorrhage and sepsis remain the major causes of complications in obstetric patients from rural areas. The common indications for mechanical ventilation were pulmonary oedema, ARDS and acute lung injury. Early initiation of mechanical ventilation upon detection of imminent.

Background: Information recorded in the 'cause of death' section of death certificates is an important source of mortality statistics. It is used for policy decisions, development of healthcare programmes and health research. Errors in death certificates can lead to inappropriate allocation of resources. Errors are universal and have been reported previously. We planned an educational intervention aimed at resident doctors from various specialties at our teaching hospital to improve the accuracy of the 'cause of death' section in death certificates., Methods: Three workshops, each of 90 minutes, were conducted for residents. A total of 198 death certificates (96 before and 102 after intervention) were audited. We compared the frequency of major and minor errors before and after the educational Intervention., Results: Following the educational intervention, there was a significant decrease in major errors such as unacceptable underlying cause of death (39.6% v. 24.5%, p = 0.034), reporting of mechanism without underlying cause of death (13.5% v. 1%, p = 0.001) and improper sequencing of events (25% v. 6%, p = 0.004). There was no significant decrease in minor errors such as absence of time intervals, use of abbreviations and reporting a mechanism with a legitimate cause., Conclusion: Both major and minor errors are common in death certification at teaching hospitals. Educational interventions can improve the accuracy of reporting in death certificates.

Bronchobiliary fistula is defined as the passage of bile in the bronchi and in the sputum (bilioptysis). This rare disorder is associated with significant morbidity. Authors review the anaesthetic management of bronchobiliary fistula and recommend the use of double lumen endotracheal tube even in cases with a closed/sealed bronchobiliary fistula.
