As anaesthesia progressed, the mean difference between the NiBP and the ABP decreased in the dependent arm and increased in the non-dependent arm. The strength of agreement between the NiBP and the ABP in various BP ranges showed moderate correlation for the dependent arm NiBP (0.45-0.54) and poor correlation (0.21-0.38) for the non-dependent arm.

The NiBP of the dependent arm correlated well with ABP in LDP under general anaesthesia (GA). It is better to defer measuring NiBP in the non-dependent arm as the correlation with ABP is poor.

The ultrasound-guided infraclavicular brachial plexus block (USG ICBPB) is a popular technique for forearm surgeries distal to the elbow. Our study details the ultrasound (US) characteristics of this block and the structures encountered by the needle in four approaches to the infraclavicular area – lateral infraclavicular (LICF), costoclavicular medial to lateral (CML) and lateral to medial (CLM) and retroclavicular (R) by anatomical dissection.

USG ICBPB was performed in 10 cadavers-5 on the right side and 5 on the left side by each of four approaches and with an 18 gauge Tuohy needle kept

, and US characteristics were noted. Anatomical dissection was done and important structures were described in detail.

Needle tip and shaft visibility were least with LICF approach and best in R approach. Needle angle correlated with chest and neck circumference in LICF and CML groups. During dissection, in all approaches, neurovascular structures have been observed in the near vicinity of the needle, especially the thoracoacromial artery (TAA) or its branches. In the R approach, the ‘blind spot’ behind the clavicle is an area where neurovascular structures were present.

The R approach gives better visibility of needle shaft beyond the clavicle, but the clavicle acts as a ‘blind-spot’ for the US beam obliterating important neurovascular structures. The various neurovascular structures the needle traverses or in its immediate vicinity, do not necessarily make the CML, CLM or R approach any better than the LICF approach.

This prospective randomised study was done to compare standard, reverse, and rotation techniques of i-gel™ placement in terms of insertion characteristics and success rate.

After institutional ethics committee approval, 135 patients aged 18-50 years, ASA I and II undergoing elective surgery under general anesthesia were included. After induction of anesthesia, i-gel™ was inserted by standard, reverse, and rotation technique in Groups I, II, and III, respectively. The primary objective was mean time of insertion. Secondary variables included ease of insertion, first attempt success rate, manoeuvres required, fiberoptic view of placement, oropharyngeal leak pressure, ease of placement of nasogastric tube, and complications if any.

Mean time of insertion was 18.04 ± 5.65 s, 15.00 ± 5.72 s and 16.12 ± 5.84 s for groups I, II, and III, respectively. Time taken for insertion was shortest and significantly lower (

= 0.048) for group II compared to group I. Insertion time was comparable between rest of groups. The overall success rate in groups I, II, and III were 91.1%, 95.6%, and 93.3% respectively (

= 0.7). The first attempt success rate was 82.2%, 89%, and 84.4% in groups I, II and III, respectively (

= 0.07). Manoeuvres were required in five (12.19%) patients in group I, four (9.30%) patients in group II, and three (7.14%) patients in group III (

= 0.602). Complications occurred in eight, three, and three patients in groups I, II, and III, respectively.

All techniques of i-gel insertion are equally good and choice of technique depends upon the experience and comfort of the investigator with the particular technique.

Patients with major burns posted for early tangential excision and skin grafting pose peculiar challenges for anaesthesiologists. The purpose of the study was to assess safety and efficacy of total intravenous anaesthesia (TIVA) with tumescent infiltration anaesthesia (TIA) for these burn procedures.

This observational single-arm study was conducted on 48 cases of a tertiary centre burn unit, requiring early tangential excision and skin grafting between third and fifth days of burn injury. TIVA was administered using a combination of intravenous (iv) infusion of injection dexmedetomidine and iv boluses of fentanyl, ketamine, propofol, midazolam and paracetamol. TIA was administered in burn wounds after aseptic preparation. Spontaneous breathing was maintained with oxygen supplementation. Haemodynamic and respiratory monitoring was done intraoperatively every 15 minutes and for 6 hours postoperatively. Modified Aldrete’s score was calculated at 10 minutes after completion of surgery. see more Statistical analysis was done using statistical package for the social science software (version 16). Descriptive statistics were used for quantitative variables.

Baseline mean HR was 106.95 ± 11.17 bpm (beats per minute). HR settled at 73.17 ± 6.97 bpm during the intraoperative period. The baseline mean arterial pressure (MAP) of 82.42 ± 10.04 mmHg was maintained at 81 ± 7.32 mmHg during the intraoperative period. In all, 95.8% achieved early recovery with mean modified Aldrete’s score of ≥9 at 10 minutes post-surgery. There was no episode of apnoea or desaturation.

TIVA in combination with TIA minimally interferes with homeostasis and promotes early recovery in patients undergoing early excision and grafting in major burns.
