Anaesthetic issues in robotic-assisted minimally invasive surgery

Biochemical implications of robotic surgery: a new frontier in the operating room

Robotic surgery represents a milestone in surgical procedures, offering advantages such as less invasive methods, elimination of tremors, scaled motion, and 3D visualization. This in-depth analysis explores the complex biochemical effects of robotic methods. The use of pneumoperitoneum and steep Trendelenburg positioning can decrease pulmonary compliance and splanchnic perfusion while increasing hypercarbia. However, robotic surgery reduces surgical stress and inflammation by minimizing tissue trauma. This contributes to faster recovery but may limit immune function. Robotic procedures also limit ischemia-reperfusion injury and oxidative damage compared to open surgery. They also help preserve native antioxidant defenses and coagulation. In a clinical setting, robotic procedures reduce blood loss, pain, complications, and length of stay compared to traditional procedures. However, risks remain, including device failure, the need for conversion to open surgery and increased costs. On the oncology side, there is still debate about margins, recurrence, and long-term survival. The advent of advanced technologies, such as intraoperative biosensors, localized drug delivery systems, and the incorporation of artificial intelligence, may further improve the efficiency of robotic surgery. However, ethical dilemmas regarding patient consent, privacy, access, and regulation of this disruptive innovation need to be addressed. Overall, this review sheds light on the complex biochemical implications of robotic surgery and highlights areas that require additional mechanistic investigation. It presents a comprehensive approach to responsibly maximize the potential of robotic surgery to improve patient outcomes, integrating technical skill with careful consideration of physiological and ethical issues.

Outpatient Robotic surgery: Considerations for the Anesthesiologist

A shortage of inpatient beds and nurses during the coronavirus disease 2019 pandemic has lent priority to safe same-day discharge after surgery. The minimally invasive nature of robotic surgery has allowed an increasing number of procedures to be done on an outpatient basis. Anesthetic management should be designed to complement the technical advantages of robotic surgery in facilitating early discharge.

Botulinum Toxin A Injection and Perianesthesia Neuromuscular Monitoring: Case Report and Review

The popularity of looking younger has been facilitated by the availability of botulinum toxin (BoNT) injection. In 2019, over 7.7 million injections of BoNT occurred, making it the number one minimally invasive cosmetic procedure in the United States. With the ease of patients obtaining BoNT in an outpatient setting, coupled with the fact that it is considered a minimally invasive procedure, most patients do not disclose the use of BoNT during the preoperative anesthesia evaluation. This case report involves a female whose recent BoNT injections interfered with neuromuscular (NM) monitoring during anesthesia. Neuromuscular monitoring was performed using the orbicularis oculi muscle with repeated train-of-four (TOF) 0/4. It was not until completion of procedure when the arms were accessible that the adductor pollicis muscle was assessed with a TOF of 2/4. During postoperative follow up, the patient revealed she had received BoNT injections prior to surgery. A review of BoNT pharmacology, barriers to NM monitoring and use of sugammadex are discussed. This case demonstrates the importance of ascertaining BoNT injection history in any case in which access to the ulnar nerve or tibial nerve is not available.

Robotic Management of Fibroids: Discussion of Use, Criteria and Advantages

Fibroids are the most common benign tumors affecting fertility and quality of life. Different methods either definitive or fertility sparing are used for their management by using open, laparoscopic and robotic techniques. This is a narrative review presenting the role and the advantages of robotic surgery in fibroids (myomectomies or hysterectomies). Such a management is effective, safe and feasible in hands of well-trained teams even for multiple, large or deep located fibroids.

Perioperative considerations for kidney and pancreas-kidney transplantation

Kidney transplantation is the treatment of choice in patients with end-stage renal disease, as it improves survival and quality of life. Living donor kidney transplant prior to pancreas transplantation, or simultaneous pancreas and kidney transplantation are discussed. Patients usually present comorbidities and extensive preoperative workups are recommended, especially cardiac assessment, though type and frequency of surveillance is not established. Nephroprotective strategies include adequate fluid status and goal-directed therapy. The conventional use of diuretics has not demonstrated a real nephroprotective effect at follow-up. Thromboprophylaxis regimes, especially for the pancreatic graft outcome, are of importance. Notably, transplantation in the obese population has increased in recent decades. Strict preoperative evaluation and pulmonary considerations must be kept in mind. Finally, robotic kidney transplant is a recent approach that presents anesthetic challenges, mainly related to steep Trendelenburg position and fluid restriction.
