Anesthesia , Analgesia

The objective of this study is to evaluate the clinical impact of the NOL nociception level index monitoring on intraoperative and post operative patient outcomes and institutional metrics when used to guide intraoperative analgesia dosing in patients undergoing spine surgery under general anesthesia when compared to a case controlled retrospective cohort.

Effective postoperative analgesia is critical for patient recovery, satisfaction, and the reduction of hospital stay duration. Continuous peripheral nerve blocks (CPNB) via catheter placement represent a cornerstone in achieving these objectives. Traditionally, follow-up for these patients has relied on standardized telephone protocols conducted by trained personnel. Original previous research in 2024 demonstrated that an automated text-messaging platform was feasible and maintained high patient satisfaction, it resulted in a significantly higher rate of unscheduled patient-initiated inquiries (28.3% vs. 6.4%) compared to traditional phone calls, likely due to a lack of adaptive response capabilities. Objective: This study aims to evaluate an enhanced technological iteration of our follow-up platform. By integrating an Artificial Intelligence (AI) interface trained on specialized clinical protocols, the new system is designed to provide automated, personalized and adaptive recommendations to patients. Methods and Intervention: The study will compare the effectiveness of this AI-driven platform against the previous version of the non-adaptive automated messaging system. The primary outcome is to compare the number of patient-initiated inquiries (re-consultations). Secondary outcomes include patient satisfaction, adherence to the follow-up protocol, and response rates from postoperative days one through three. Impact: The investigators hypothesize that the integration of AI will optimize human resources and improve patient autonomy without compromising safety or satisfaction, ultimately providing a scalable model for postoperative regional analgesia monitoring.

Effective perioperative pain management remains a cornerstone in enhancing recovery and improving patient outcomes in laparoscopic cholecystectomy. This minimally invasive procedure, although less traumatic compared to open surgery, can still lead to significant postoperative pain, particularly in the early hours following the operation. Insufficient pain control may result in delayed mobilization, prolonged hospital stays, and increased opioid consumption, which are associated with adverse side effects and a heightened risk of complications . Regional anesthesia techniques have garnered significant attention for their ability to provide localized, opioid-sparing analgesia, thereby improving postoperative recovery profiles.External Oblique Intercostal Plane Block (EOIP) is a relatively new regional anesthesia technique targeting the intercostal nerves (T7-T11) as they traverse the plane between the external and internal oblique muscles. This block has demonstrated efficacy in controlling postoperative pain for upper abdominal surgeries, including laparoscopic cholecystectomy. By selectively anesthetizing the sensory branches of the thoracoabdominal nerves, the EOIP block provides localized analgesia with minimal motor blockade, making it an ideal choice for early mobilization (Ouchi et al., 2020).Recent advancements in ultrasound-guided techniques have improved the precision and safety of the EOIP block, allowing for consistent blockade of the targeted nerves. Clinical trials have highlighted its ability to reduce the pain significantly in the first 24 hours postoperatively, along with a marked decrease in the need for rescue analgesics. Tranrversus abdominis plane block (TAP) , first described in the early 2000s, has undergone several modifications to improve its efficacy in abdominal surgeries. The subcostal TAP block targets the anterior branches of the lower thoracic nerves (T6-T9) to provide analgesia to the upper abdominal wall. This technique is particularly suited for laparoscopic cholecystectomy, where the pain originates predominantly from the pari0etal peritoneum and abdominal wall incisions.The single puncture technique of Rectus sheath block (RSB) combined with transversus abdominis plane block (TAPB) represents a more streamlined approach to abdominal wall analgesia. ultrasonography (US) guidance for peripheral nerve blocks has become more and more popular. Transversus abdominis plane block (TAPB) and US-guided rectus sheath block (RSB) have been utilized in abdominal surgeries and have shown strong analgesic effects. Prior researches has demonstrated that in abdominal surgery, US-guided (TAPB) in conjunction with (RSB) had superior analgesic effects than either (TAPB) or (RSB) alone. Currently, multipoint nerve block procedures are generally applied in clinical practice, but they are difficult and can increase the patient's suffering. A novel method is proposed based on the neuromuscular anatomy and the location of the incisiopn in laparoscopic upper abdominal surgery: US-guided transverse abdominis plane and rectus sheath block one-puncture .

The aim of this study to evaluate efficacy of ultrasound guided regional anesthesia in performing awake tympanoplasty surgery versus traditional general anesthesia

Up to 30% of patients undergoing intracranial surgery present moderate to severe pain. In this type of surgery, the restriction of the pharmacopoeia, which goes against the concept of multimodal analgesia, results in the important use of opioids not without consequences in terms of complications. Numerous studies have highlighted the benefits of scalp blocks in postoperative pain. The originality of this study lies firstly in the fact that the scalp blocks will be guided by ultrasound and secondly, the incidence of severe pain after scalp blocks will be evaluated
