Robotic surgery has revolutionised minimal access surgery by enhancing surgical technique and at the same time minimising or negating human errors., Paediatric robotic surgery (PRS) can be performed for a wide range of indications ranging from urological surgery such as pyeloplasty to congenital cardiac defect repairs. Anaesthetic management of such cases offers unique challenges with respect to paediatric physiology and its interaction with iatrogenic pneumoperitoneum. The following case highlights nuances of management of such a case presenting to our institute.
A 1-month 23-day-old male infant weighing 3.7 kg, suffering from left pelvi-ureteric junction obstruction with hydronephrosis, was posted for robotic pyeloplasty. Pre-anaesthetic evaluation revealed no significant history or findings in examination and laboratory results. On the day of surgery after appropriate age-specific preparation of the theatre, general anaesthesia was induced and the trachea was intubated with a 3-mm Microcuff® polyurethane endotracheal tube (ETT). A precordial stethoscope was secured. Warmed 2% dextrose in a lactated ringer solution was given for intraoperative fluid requirements. Volume-controlled mechanical ventilation with appropriate pressure limitation (20–22 cmH2O) was used. Anaesthesia was maintained with sevoflurane, intermittent atracurium and fentanyl IV. Nitrous oxide was avoided.
A slight right lateral position was achieved by elevating the loin with a soft bolster and secured to the table with padded straps. Extra padding was applied at all pressure points. The face and ETT were covered with cotton padding to prevent inadvertent injury from the moving arms of the robot [[Video 1] (online)]. Pneumoperitoneum was created slowly with an initial intra-abdominal pressure (IAP) of 8 mmHg after insertion of the umbilical port (8 mm robotic). Urinary bladder and stomach were decompressed prior to port insertion. Rest of the three ports were inserted under vision, two operative (8 mm) and one assistant port (5 mm) [Figure 1]. Docking of ports was initiated with the daVinci® robotic system. After docking, IAP was reduced to 6 mmHg maintenance pressure [Figure 2]. The ETT position was rechecked after establishing pneumoperitoneum and after position changes. Intra-operative ventilation was managed by titrating minute ventilation to obtain an ETCO2 of 35–40 mmHg.
Haemodynamic parameters remained stable during the course of the surgery. Sympathetic response to pneumoperitoneum was managed with aliquots of IV fentanyl and increasing depth of inhalational agent. Airway pressures and IAP were noted periodically. Urine catheter was clamped during most part of the surgery to provide good surgical conditions over the ureter and output was estimated by visual inspection of urine dribbling in the surgical field. The patient was checked intermittently under the drapes to make sure the robotic arms were away from the body. Postoperatively, feeding was resumed after 2 h.
Pelvic robotic surgeries including urological procedures offer an added advantage and better surgical access compared to conventional laparoscopic surgery., PRS is less frequently being performed in younger infants less than 6 months, mostly because of equipment-related issues. But due to newer paediatric-specific instruments and formalisation of PRS systems in hospitals, anaesthesiologists will encounter much younger patients coming for such surgeries.
Basic principles of PRS management essentially remain the same as for conventional paediatric laparoscopic surgery. These broadly include fluid management, countering systemic and endocrine effects of pneumoperitoneum, ventilation management, and avoiding and managing complications related to carbon dioxide absorption. A high index of suspicion should be kept for detection of complications such as pnuemothorax and venous air embolism. PRS offers other challenges such as restricted access to the patient once docking of robotic arms has taken place. Thus, all airway, IV and monitoring tubes and lines should be properly secured prior to draping and docking. Sometimes, steep extreme surgical positions for prolonged periods may be required, especially in urinary bladder surgery. General measures to prevent hypothermia, hypercarbia, hypoxemia and fluid overload should also be taken.
