BACKGROUND AND AIMS: Multiple sources of medical oxygen, namely liquid medical oxygen (LMO) tanks, pressure swing adsorption (PSA) plants, concentrators, and gaseous cylinders, are available at different healthcare facilities. These sources of oxygen have varying installation and operational costs. In low-resource settings, it is imperative to utilise these assets optimally. This study investigated the operational costs of multiple oxygen sources available at a healthcare facility. METHODS: A Microsoft (MS) Excel-based model was developed to analyse and compare the oxygen manufacturing costs (in ₹/m3 ) using PSA plants and procurement costs (in ₹/m3 ) of LMO and third-party vendor-refilled cylinders...

BACKGROUND AND AIMS: There is limited data on the effects of norepinephrine on neonatal outcomes and maternal complications relative to other vasopressors. The study aimed to compare neonatal outcomes and maternal complications after bolus intravenous doses of phenylephrine and norepinephrine for post-spinal hypotension in elective caesarean section women. METHODS: This randomised study was done on 100 elective caesarean section women under spinal anaesthesia. Block randomisation divided women into two groups to receive intravenous phenylephrine 50 μg bolus (Group A) or norepinephrine 5 μg bolus (Group B) following post-spinal hypotension...

Sickle cell disease is characterised by episodes of vaso-occlusive crisis, a painful complication. Regional anaesthesia has shown promising results in reducing opioid consumption and pain scores. Patients with vaso-occlusive crises who underwent regional anaesthesia in the paediatric intensive care unit were studied. Data regarding pain location, regional analgesia technique, the local anaesthetic used and dose, daily opioid consumption, daily pain scores, use of adjuvants and complications were recorded. The primary outcome was to evaluate the effect of regional anaesthesia on opioid consumption...

BACKGROUND AND AIMS: Perioperative intravenous (IV) infusions of lidocaine and esketamine reduce postoperative pain, but there are few studies on the quality of recovery and patients' emotional states postoperatively. We aimed to explore the effects of perioperative IV lidocaine and esketamine on the quality of recovery and emotional state after thyroidectomy. METHODS: In this randomised trial, 137 patients undergoing thyroidectomy were randomly assigned to three groups: a lidocaine group (Group L), an esketamine group (Group E) and a normal saline placebo group (Group C)...

BACKGROUND AND AIMS: Apprehension of pain due to a spinal needle is often a cause of anxiety and refusal. ShotBlocker provides non-painful physical stimulation, inhibiting pain perception. The vapocoolant spray contains ethyl chloride vapours, rapidly raising the skin temperature and hampering the transmission of noxious stimuli. The present study compared the effectiveness of the ShotBlocker device and the vapocoolant spray in reducing spinal needle-associated pain in primigravida women undergoing elective lower-segment caesarean section (LSCS)...

BACKGROUND AND AIMS: We compared classical (medial) and modified (lateral) thoracolumbar interfascial plane block (TLIP) with only general anaesthesia (GA) using multimodal analgesia in patients undergoing lumbar disc surgeries. METHODS: In this study, 100 patients aged 18-70 years were randomised to Group cTLIP (conventional TLIP block with 20 mL of 0.25% ropivacaine with GA), Group mTLIP (modified TLIP block with 20 mL of 0.25% ropivacaine with GA), and Group C (only GA using multimodal analgesia)...

BACKGROUND AND AIMS: Peri-capsular nerve group (PENG) block is a novel ultrasound (US)-guided technique to achieve regional analgesia in hip fractures. We compared the effectiveness of two doses of 0.25% bupivacaine (20 mL and 15 mL) in the US-guided PENG block for positioning patients for sub-arachnoid block (SAB) during hip fracture surgery. METHODS: The randomised trial included 60 patients aged 40-90 years undergoing hip fracture surgery under SAB. PENG block was given by a US-guided approach with the patient in a supine position 20 minutes before SAB, and a total of 20 mL and 15 mL of bupivacaine (0...

BACKGROUND AND AIMS: No studies have evaluated the relationship between maternal arterial partial pressure of carbon dioxide (mPaCO2 ) and umbilical cord venous partial pressure of carbon dioxide (PCO2 ) in critically ill pregnant women at delivery. Based on the studies in healthy pregnant women, an mPaCO2 target of ≤50 mmHg is a suggested threshold during mechanical ventilation in critically ill parturients. We evaluated the relationship between mPaCO2 and neonatal cord gases in critically ill parturients at delivery as the primary objective...

BACKGROUND AND AIMS: Laryngoscopy and tracheal intubation require an adequate depth of anaesthesia. The study's primary objective was to compare the time needed to achieve the bispectral index (BIS)-guided adequate depth of anaesthesia for endotracheal intubation using fentanyl and dexmedetomidine. METHODS: After institutional ethics committee clearance and written informed consent, this randomised study was conducted on 140 patients of either gender between 18 and 60 years who were scheduled for elective surgeries under general anaesthesia...

BACKGROUND AND AIMS: Short-term hypotension after general anaesthesia can negatively impact surgical outcomes. This study compared the predictive potential of the pleth variability index (PVI), pulse pressure variability (PPV), and perfusion index (PI) for anaesthesia-induced hypotension. This study's primary objective was to evaluate the predictive potential of PI, PVI, and PPV for hypotension. METHODS: This observational study included 140 adult patients undergoing major abdominal surgery under general anaesthesia...

Surgery for excision of juvenile nasopharyngeal angiofibroma (JNA) carries the possibility of massive life-threatening haemorrhage. Anaesthetic management aims to maintain haemodynamic stability and reduce blood loss. This case series describes the application of the bundled approach as a multimodal blood loss prevention bundle (MBLPB). Twenty patients underwent 23 surgeries with MBLPB. The blood loss and the number of units of blood transfused were recorded. The surgeon satisfaction score was assessed. The median [interquartile range (IQR)] estimated blood loss was 1300 (650-2350) ml...
