ReviewAdvances in Anesthesia Techniques for Postoperative Pain Management in Minimally Invasive Cardiac Surgery: An Expert Opinion.
Minimally invasive cardiac surgery (MICS) often leads to severe postoperative pain. At present, multimodal analgesia schemes for MICS have attracted much attention, and the application of various chest wall analgesia techniques is becoming increasingly widespread. ⋯ This article provides an overview of the anatomy and procedures involved in these analgesic techniques, their mechanisms of action, and the latest clinical trial evidence. It also evaluates their progress in MICS, compares their advantages and disadvantages, and discusses practical challenges.

The purpose of this review is to provide the most recent update and summary on the consideration, benefits and application of regional anesthesia in the ICU setting, as it pertains to the management of perioperative pain. ⋯ Regional anesthesia and analgesia have become ubiquitous in the perioperative setting, with numerous indications and benefits. As integral part of the multimodal analgesia approach, various regional blocks have been increasingly utilized in critically ill patients. We focus this review on various regional techniques employed for critically ill patients after cardiac, thoracic, and major abdominal surgery, including neuraxial and novel truncal blocks. Effective pain management in critically ill patients poses many challenges and is extremely important. Regional anesthesia, in combination with other analgesia modalities, while still under-utilized, can help reduce acute perioperative pain, stress response, opioid use and related side effects and expedite recovery and improve clinical outcomes.

Ketamine, an N-methyl-D-aspartic acid receptor antagonist that was first discovered in 1962, has become established in anaesthesia providing dose-dependent anaesthetic, sedative, and analgesic effects. Ketamine, however, also acts on a wide range of other cellular targets, resulting in interesting and diverse effects on both physiological and pathological processes. Potential beneficial properties of ketamine include cardiovascular stability for patients undergoing sedation or anaesthesia, analgesia in both acute and chronic pain, bronchodilation in severe refractory asthma, anti-inflammatory properties particularly in sepsis, tumour inhibition, and antidepressant properties with marked ability to reverse suicidal ideation. ⋯ This review explores the diverse properties and therapeutic potentials of ketamine being investigated across different fields whilst also identifying areas for ongoing and future research. Given the diverse range of potential benefits and promising early work, ketamine should be the focus of ongoing research in multiple different specialty areas. This includes areas relevant to anaesthesia and perioperative medicine, such as acute and chronic pain management, ICU sedation, and even tumour suppression in those undergoing surgical resection of malignancies.

Review Meta Analysis Comparative Study
The impact of spinal versus general anesthesia on the variability of surgical times: a systematic review and meta-analysis.
With spinal anesthesia, when cases are taking longer than usual, there may be behavioural tendencies for surgical teams to work more quickly. We conducted a systematic review with meta-analysis to examine standard deviations of surgical times for single-dose spinal anesthetics versus general anesthesia. We compared ratios of mean surgical times as a secondary endpoint. ⋯ PROSPERO ( CRD42023461952 ); first submitted 8 September 2023.

Review Meta Analysis Comparative Study
Comparison of different monitors for measurement of nociception during general anaesthesia: a network meta-analysis of randomised controlled trials.
To avoid underdosing or overdosing of analgesic medications, a variety of nociception monitors that use distinct techniques have been developed to quantify nociception during general anaesthesia. Although prior meta-analyses have examined the behaviour of nociception monitors vs standard care protocols, they did not include the potentially valuable data for monitor-to-monitor comparisons. In order to capture these data fully and compare the behaviour of these monitors, we conducted a systematic search and network meta-analysis. ⋯ Apart from pupillometry, no monitors demonstrated a significant effect on intraoperative opioid consumption. Secondary outcomes indicate limited clinical benefit for patients when using these monitors.
