Navigating Nutritional Strategies: Permissive Underfeeding in Critically Ill Patients.

Nutritional support is a critical component of care for critically ill patients, impacting their recovery and overall prognosis. Traditional approaches to feeding in the intensive care unit (ICU) have focused on meeting estimated energy requirements, often resulting in unintended consequences such as overfeeding and associated complications. Permissive underfeeding, a concept gaining attention recently, offers a more controlled approach by intentionally providing fewer calories than traditionally recommended. This comprehensive review explores the rationale, evidence, and practical considerations surrounding permissive underfeeding in critically ill patients. We discuss the physiological basis of permissive underfeeding, its potential benefits in mitigating the risks of overfeeding, and the challenges associated with implementation in clinical practice. Through an analysis of critical studies and clinical trials, we evaluate the comparative effectiveness of permissive underfeeding versus traditional feeding methods and examine its impact on patient outcomes. Recommendations for patient selection, monitoring, and future research directions are provided to guide clinicians in optimizing nutritional support strategies for critically ill individuals. By considering the role of permissive underfeeding alongside traditional feeding approaches, healthcare professionals can tailor nutritional interventions to individual patient needs, ultimately improving outcomes in the ICU.

Exploring Ciprofol Alternatives: A Comprehensive Review of Intravenous Anesthesia Options.

Ciprofol is a recently developed, short-acting γ-aminobutyric acid receptor agonist sedative that is more potent than propofol. Still, there have been few clinical studies of this agent to date. This review explores alternative intravenous anesthesia options to ciprofol, considering their pharmacology, clinical efficacy, safety profile, and practical considerations. While ciprofol offers advantages such as rapid onset and predictable offset, concerns regarding its safety profile and individual variability in response have prompted the search for alternatives. Propofol, etomidate, ketamine, and dexmedetomidine are discussed as established options, each with unique characteristics and potential benefits. Emerging agents, including remimazolam, sufentanil, alfaxalone, and brexanolone, are examined for their potential role in anesthesia management. Recommendations for future research include large-scale comparative studies, optimization of dosing strategies, and personalized approaches guided by pharmacogenomic insights. Ultimately, the future of intravenous anesthesia lies in a multifaceted approach that integrates evidence-based practices, technological innovations, and individualized patient care to enhance safety, efficacy, and patient satisfaction across the perioperative continuum. Collaboration among stakeholders will be crucial in advancing the field and shaping the future landscape of intravenous anesthesia options.

Anesthetic Management of a Down Syndrome Patient for Ventricular Septal Defect Repair: A Case Report.

It is commonly known that Down syndrome (DS) and congenital cardiovascular abnormalities go hand in hand. Most frequently, complete atrioventricular septal abnormalities have been linked to DS. Along with DS, ventricular septal defect (VSD), atrial septal defect, tetralogy of Fallot, and patent ductus arteriosus have also been reported. We present a case of DS with VSD who underwent VSD correction. Echocardiography prompted the diagnosis, which was then confirmed by surgery. The patient was successfully transferred out of the hospital. After correcting the VSD, the survival and quality of life of the DS patient have improved.

A Multidisciplinary Approach to Tracheoesophageal Fistula Repair in a Newborn: A Case Report.

This case report details the emergency management and successful surgical repair of a tracheoesophageal fistula (TEF) in a newborn delivered by lower segment cesarean section. Despite immediate crying after birth, the neonate's distress was evident, with an Apgar score of 4, prompting an urgent referral to the Neonatal ICU (NICU). Diagnostic investigations, including ultrasonography and two-dimensional echocardiography (2D Echo), revealed associated anomalies, such as a patent ductus arteriosus, arterial septal defect, and a TEF. An anaesthetist was urgently involved due to postnatal desaturation, leading to challenging intubation and surgical repair performed under general anaesthesia, which involved separating the trachea from the oesophagus. Postoperative imaging confirmed the successful closure of the fistulous connection. This case highlights the significance of prompt diagnosis, collaborative management, and surgical intervention in optimising outcomes for neonates with complex congenital anomalies like TEF.

Anaesthetic Challenges in a Patient of Ludwig's Angina: A Case Report.

Anaesthesiologists have difficult airways to manage while treating patients with severe neck infections. Ludwig's angina patients who are unable to adequately control their airways may pass away. In this article, we go through the anaesthetic management during an emergency drainage procedure for Ludwig's angina. In severe cases of Ludwig's angina, awake fiberoptic intubation under topical anaesthetic is the most effective strategy to maintain the airway. An awake tracheostomy may be the best alternative when awake fiberoptic bronchoscopy is not possible.

Comparison of Inhalational Vital Capacity Induction with Sevoflurane to Intravenous Induction with Propofol for Insertion of Laryngeal Mask Airway in Adults: A Randomized Study.

BACKGROUND: Since the development of laryngeal mask airway (LMA) by Dr. Brain, it is extensively used for airway management; satisfactory insertion of LMA requires administration of an induction agent and suppression of airway reflexes. Among intravenous agents, propofol has been the drug of choice in view of better safety profile, relaxation and depression of upper airway reflexes. Sevoflurane on the other hand, with pleasant odor, nonirritating to the airways and with bronchodilator property are best among the volatile induction agents. While it is true both propofol and sevoflurane have their merits, still both have certain limitations. We aimed to compare the quality and ease of LMA insertion, hemodynamic changes, and complications with inhalation of 8% sevoflurane vital capacity breath and propofol. MATERIALS AND METHODS: A prospective randomized study of 100 American Society of Anaesthesiologists' Class I and II patients was conducted equal distribution among two groups with 50 each undergoing gynecological procedures under general anesthesia. Group P received injection propofol and Group S received sevoflurane. At the end point of induction, the LMA insertion was attempted. Scoring systems were used to grade the conditions for insertion of the LMA. Induction characteristics, hemodynamic changes, and complications were assessed. RESULTS: Sevoflurane took a longer time for induction and jaw relaxation than propofol. There was no statistically significant difference between the two groups, with respect to LMA insertion time, and conditions. Apnea time was more in propofol group. Fall in heart rate and mean blood pressure was more in propofol. CONCLUSION: Propofol is associated with faster induction while sevoflurane is associated with good hemodynamic stability.
