Ultrasound-guided modified serratus anterior plane block for perioperative analgesia in breast oncoplastic surgery: A case series
We present a series of 11 patients where ultrasound-guided SAP block was used as part of multimodal analgesia in breast reconstruction surgery using latissimus dorsi (LD) myocutaneous flap after mastectomies. This resulted in excellent analgesia in the perioperative period and minimal use of intravenous analgesics. The SAP block technique described here is safe and also provides effective analgesia in breast reconstruction surgery with LD flap. (Source: Indian Journal of Anaesthesia)

Comparison of bispectral index targeted end-tidal concentration of desflurane during three phases of orthotopic liver transplantation
Conclusion: In patients undergoing LD-OLT, BIS monitoring guidance of depth of desflurane GA suggests lower desflurane requirements during ‘anhepatic’ and the ‘neohepatic’ phase of surgery. Also, the desflurane requirement is greater in patients with lesser severity of liver disease. (Source: Indian Journal of Anaesthesia)

Novel reversal agents and laboratory evaluation for direct-acting oral anticoagulants (DOAC): An update
Shagun B Shah, Akhilesh Pahade, Rajiv ChawlaIndian Journal of Anaesthesia 2019 63(3):169-181 Novel oral anticoagulants (NOACs) are no longer “novel” but their reversal agents definitely are. Although NOACs enjoy high clinical efficacy, monitoring and reversal of their effect is a challenge which this review attempts to surmount. Ideally, for NOAC activity measurement, specific anti-Factor IIa levels and anti -Factor Xa levels should be monitored (chromogenic assays), but such tests are not readily available. Modifications of the existing coagulation tests catering to this unmet need for quantification of DOAC ...
