This case report details the complex perioperative care of a 22-day-old male neonate, born at 27 weeks of gestation, who required surgical intervention for an incarcerated inguinoscrotal hernia. Case Presentation The neonate with post conception age of 30 weeks, born weighing 1.225 kg, presented with a right scrotal swelling diagnosed as an incarcerated inguinoscrotal hernia. His early postnatal course was complicated by respiratory distress syndrome (RDS), necessitating mechanical ventilation and surfactant therapy. A multimodal, opioid-free anaesthesia regimen was conceived to minimize the risk of postoperative apnoea. Intraoperative care focused on maintaining stable oxygenation, normothermia, and hemodynamic parameters. Anaesthesia was induced using ketamine and maintained with mixture of air/Oxygen and Sevoflurane. Ultrasound guided caudal block with Levo bupivacaine was administered to address perioperative pain. The neonate was ventilated intraoperatively in pressure-controlled mode and postoperatively in P-SIMV mode, with a smooth transition to CPAP and then to room air. The patient recovered without complications, demonstrating the effectiveness of the anaesthetic strategy employed. Conclusion This case highlights the complexities of perioperative management in extremely preterm neonates, emphasizing the importance of an individualized, multidisciplinary approach. The successful outcome underscores the efficacy of opioid-sparing anaesthesia and meticulous perioperative care in mitigating the risks associated with surgery in these vulnerable preterm neonates. This report contributes to the growing body of knowledge on optimizing perioperative strategies for preterm neonates. Preterm neonate perioperative management opioid-free anesthesia caudal block neonatal surgery Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Introduction The perioperative management of extremely preterm neonates represents one of the most challenging role in paediatric anaesthesia due to their immature physiology and increased susceptibility to a spectrum of perioperative complications. Preterm neonates—particularly those born before 28 weeks of gestation—are characterized by underdeveloped organ systems, including incomplete pulmonary surfactant synthesis, fragile cardiovascular regulation, and metabolic immaturity, leading to elevated risks of respiratory distress syndrome, cardiovascular instability, hypoglycaemia, and temperature dysregulation. [ 1 , 2 , 3 ]. These physiological vulnerabilities the anaesthetic management more complex and necessitate careful and evidence-based strategies focused to the unique needs of the neonate. This case report presents the perioperative management of a 22-day-old male neonate born at 27 weeks of gestation (Post conception age of 30weeks + 1day). The neonate, classified as very preterm with a very low birth weight of 1.225 kg, was diagnosed with a right incarcerated inguinoscrotal hernia. The management of such a high-risk neonate required careful consideration of the unique physiological challenges associated with prematurity, including respiratory, cardiovascular, and metabolic instability. Case presentation A 22-day old male neonate presented with a right scrotal swelling whose antenatal history was marked by oligohydramnios detected during the third trimester, necessitating close monitoring. The mother had an uneventful first and second trimester. The neonate was delivered via emergency lower segment caesarean section (LSCS) due to spontaneous labour and oligohydramnios at 27 weeks of gestation. The baby had a birth weight of 1.225 kg, an Apgar score of 7 at 1 minute and 8 at 5 minutes, and required immediate NICU admission due to respiratory distress syndrome (RDS) for which the neonate was initially intubated and received surfactant therapy. He was managed on synchronized intermittent mandatory ventilation (SIMV) for 4 days, followed by continuous positive airway pressure (CPAP) until day 11 of life, when he was successfully weaned to room air. On general and systemic examination, the neonate was alert, with good hydration and no signs of respiratory distress or cardiovascular instability. Blood investigations were within normal limits. Ultrasound abdomen revealed an incarcerated inguinoscrotal hernia. The herniated bowel loop showed no signs of peristalsis but maintained normal vascularity. Emergency right open herniotomy was planned. The neonate was kept nil per oral (NPO) for 4 hours prior to surgery, with maintenance fluid isolyte-p at 6ml/hr provided via an infusion pump. The operating room was pre-warmed to 35–37°C, and warmed fluids were used to prevent hypothermia. Due to the difficult airway anticipated from the neonate’s anatomy (larger head, narrow nasal passage, larger tongue, floppy epiglottis), airway cart to manage difficult airway including, video laryngoscope (VDL) was kept on standby Hemodynamic monitoring was carefully conducted during the transfer to the operating theatre. The neonate was preoxygenated ( Fig. 1 ) and premedicated with Inj.Atropine and Inj.Ondansetron. An opioid-free, multimodal anaesthesia approach was selected to prevent the risk of apnoea. Inj.Ketamine was used for induction, followed by Inj.Cisatracurium for muscle relaxation to secure the airway with a cuffed endotracheal tube. The baby was ventilated with pressure-controlled ventilation ( Fig. 2 ) with minimal tidal volume of 8ml/kg and the plane was maintained with air/oxygen and Inh.Sevoflurane. The ventilation parameters were carefully adjusted to maintain oxygen saturation between 88–92%, avoiding the use of Inh.Nitrous oxide to prevent bowel distension. Caudal analgesia was administered using 1ml of Inj.0.25% Bupivacaine, guided by ultrasound to locate the caudal space accurately ( Fig. 3 ,4). Intraoperative fluids were maintained at 6 ml/hr using an infusion pump, and strict monitoring of blood glucose and core temperature was performed throughout the surgery. Intraoperatively, a very rare finding of a perforated appendix within the hernial sac was encountered, necessitating immediate surgical intervention to prevent further complications. Postoperatively, the neonate was shifted back to the NICU for elective mechanical ventilation in SIMV mode, later transitioning to nasal CPAP(Fig. 5 ). Hemodynamic monitoring continued postoperatively to ensure stability. Antibiotics were administered as per the neonatologist orders to prevent infection. The neonate was successfully weaned off from mechanical ventilation within 6 hours post-surgery following adequate respiratory function without signs of apnoea. Baby recovered well, gained weight and was eventually discharged in good health. Discussion The case illustrates the significant perioperative challenges in managing a very preterm neonate, including the risk of difficult airway, respiratory depression, cardiovascular instability, hypoglycaemia, hypothermia, and postoperative apnoea. Careful fluid management is critical and the individualized fluid therapy in necessary in neonates due to their limited physiological reserves and higher vulnerability.[ 4 ] Caudal blockade is a effective and safe technique for postoperative pain management in paediatric patients. The technical difficulty of administering caudal analgesia in a neonate with immature anatomy was successfully managed with ultrasound guidance. Ultrasound guidance improves the success rate of caudal blockade and reduces the risk of complications compared to landmark-based techniques.[ 5 , 6 ] The decision to use opioid-free anaesthesia was crucial in minimizing the risk of postoperative apnoea, a common complication in preterm infants.[ 7 , 8 ] Macrae et al, highlighted that the premature neonates require specialized anaesthetic care due to their immature physiology. Anaesthetic techniques should be tailored to minimize risks and optimize outcomes. Additionally, attention to fluid management and thermoregulation is critical in the perioperative period.[ 9 ] Subramaniam et al, supports and expands on the anaesthetic considerations and provides additional information on the physiological differences between preterm and term neonates and how these differences impact anaesthetic management.[ 10 ] Taneja B et al, discussed the unique physiological characteristics of preterm neonates, such as Immature organ systems, limited cardiovascular reserve, increased sensitivity to anaesthetic agents.[ 11 ] This case highlights the importance of a multidisciplinary approach, involving anaesthesiologists, surgeons and neonatologists to address the unique needs of preterm neonates during surgery. Conclusion This case underscores the complexity of perioperative care in extremely preterm neonates, emphasizing the need for careful planning, specialized monitoring, specialized techniques, and vigilant postoperative management to ensure favourable outcomes. The successful management of this case demonstrates the critical role of a tailored anaesthesia plan and close interdisciplinary collaboration in addressing the multifaceted challenges presented by such high-risk patients.

The mother had an uneventful first and second trimester. The neonate was delivered via emergency lower segment caesarean section (LSCS) due to spontaneous labour and oligohydramnios at 27 weeks of gestation. The baby had a birth weight of 1.225 kg, an Apgar score of 7 at 1 minute and 8 at 5 minutes, and required immediate NICU admission due to respiratory distress syndrome (RDS) for which the neonate was initially intubated and received surfactant therapy. He was managed on synchronized intermittent mandatory ventilation (SIMV) for 4 days, followed by continuous positive airway pressure (CPAP) until day 11 of life, when he was successfully weaned to room air. On general and systemic examination, the neonate was alert, with good hydration and no signs of respiratory distress or cardiovascular instability. Blood investigations were within normal limits. Ultrasound abdomen revealed an incarcerated inguinoscrotal hernia. The herniated bowel loop showed no signs of peristalsis but maintained normal vascularity.
