Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) for primary peritoneal malignancies or peritoneal spread of malignant neoplasm is being done at many centres worldwide. Perioperative management is challenging with varied haemodynamic and temperature instabilities, and the literature is scarce in many aspects of its perioperative management. There is a need to have coalition of the existing evidence and experts' consensus opinion for better perioperative management. The purpose of this consensus practice guideline is to provide consensus for best practice pattern based on the best available evidence by the expert committee of the Society of Onco-Anaesthesia and Perioperative Care comprising perioperative physicians for better perioperative management of patients of CRS-HIPEC.

Artificial intelligence in perioperative management of major gastrointestinal surgeries

This randomised, double-blind study was designed to compare the duration of analgesia and adverse effects following intrathecal administration of dexmedetomidine or clonidine, both with bupivacaine, in trauma patients. Ninety adult trauma patients of American Society of Anesthesiologists physical status I—II, scheduled for lower limb surgery under subarachnoid block, were randomly allocated to one of three groups. All groups received hyperbaric bupivacaine 0.5% 3 ml, to which was added saline 0.5 ml (Group B): clonidine 50 μg (Group C) or dexmedetomidine 5 μg (Group D). The onset and duration of sensory and motor blockade, severity of postoperative pain, time to first rescue analgesia and total analgesic requirement for 24 hours were noted. There was no significant difference in the onset time of the block but the duration of sensory and motor blockade was prolonged in Groups C and D, compared with Group B. The time to analgesia was significantly prolonged in Group D (824±244 minutes) compared with Group C (678±178 minutes; P=0.01), the latter being longer than Group B (406±119 minutes; P=0.0001). Postoperative pain scores were lower in Groups C and D compared with Group B. The requirement for rescue analgesia during the first 24 postoperative hours was significantly less in Groups C and D as compared to Group B ( P=0.0001), but comparable between Group C and D ( P=0.203). In conclusion, dexmedetomidine 5 μg added to intrathecal bupivacaine 15 mg produces longer postoperative analgesia than clonidine 50 μg among trauma patients undergoing lower limb surgery.

Postoperative complications and critical care management after cytoreduction surgery and hyperthermic intraperitoneal chemotherapy: A systematic review of the literature

The All India Difficult Airway Association 2025 Adult guideline provides guidance for the management of an unanticipated difficult airway under general anaesthesia. The American Heart Association (AHA) Class of Recommendation and Level of Evidence was used. In addition, for interventions where the evidence was absent or weak, a Delphi process among airway experts was convened to generate expert consensus statements. The most significant difference from the 2016 guidelines is providing guidance for a failed supraglottic airway (SGA) insertion, tracheal intubation, face mask ventilation, or other strategies commonly used as part of the primary airway plan under general anaesthesia, not restricting to a failed intubation. Airway assessment should be routinely performed to identify an anatomical as well as the physiologically difficult airway. Peri-intubation oxygenation with pre-oxygenation and apnoeic oxygen with nasal oxygen (10–15 L/min) or high-flow nasal oxygen increases the safe apnoea time. Videolaryngoscopy and adjuncts such as stylets and bougies improve first pass intubation success. Tracheal tube position should be confirmed by waveform capnography. If the primary airway plan fails, activate ‘Code D’ as the hospital emergency code to call for help. Airway rescue should then be attempted with any of the three devices (tracheal tube, SGA, or face mask), and switching promptly between them as needed, with no hierarchy, until effective ventilation and adequate oxygen saturation (SpO₂) are achieved. Optimise patient position, ensure neuromuscular blockade, and consider changing the tools, technique, or operator. Allow up to three failed attempts with these devices provided the SpO ₂ remains ≥95%. Complete ventilation failure (ventilation using a tracheal tube, SGA, and face mask have all failed, even if oxygenation may be maintained) is the trigger to perform an emergency cricothyroidotomy , preferably by a surgical approach. Team debriefing, team support, patient and family counselling, and documentation are paramount after encountering an unanticipated difficult airway.

Rapunzel Syndrome is a rare trichobezoar, involving strands of swallowed hair extending as a tail through the duodenum, beyond the stomach. Trichobezoar usually occur in patients with history of trichotillomania, characterized by compulsive behavioral disorder of pulling own hairs, combined with trichophagia that consists of ingesting that hairs. It typically occurs in stomach and rarely affects the small intestine. Trichobezoars are more common in adolescent females. Common presentation is gastrointestinal tract obstruction with nausea and vomiting, gut perforation, acute pancreatic necrosis, obstructive jaundice, hypochromic anemia, vitamin B12 deficiency, weight loss, an abdominal mass, or other serious problems. Intestinal obstruction due to trichobezoar is extremely rare. We are here reporting a large trichobezoar in a 3-year-old male child who presented to the emergency department with thread protruding from mouth with no sign of hair loss on body.
