“…The steep Trendelenburg position also has a negative effect on respiratory mechanics, decreasing pulmonary compliance and functional residual capacity [56,57]. Arterial oxygenation is also significantly decreased during Trendelenburg positioning [58].…”

“…The blood flow velocity waveform also can be used to measure flow time, which is the time from the start of the waveform upstroke to return to baseline. When corrected for HR, flow time is found to be a sensitive measure of LV filling, thus an accurate RV preload measurement [102].…”

Goal-directed fluid therapy (GDFT) is usually recommended in patients undergoing major surgery and is essential in enhanced recovery after surgery (ERAS) protocols. This fluid regimen is usually guided by dynamic hemodynamic parameters and aims to optimize patients' cardiac output to maximize oxygen delivery to their vital organs. While many studies have shown that GDFT benefits patients perioperatively and can decrease postoperative complications, there is no consensus on which dynamic hemodynamic parameters to guide GDFT with. Furthermore, there are many commercialized hemodynamic monitoring systems to measure these dynamic hemodynamic parameters, and each has its pros and cons. This review will discuss and review the commonly used GDFT dynamic hemodynamic parameters and hemodynamic monitoring systems.

Mininimally invasive surgery has become one of the most popular ones over the last few decades due to many benefits. The advantages are minimal surgical incision, reduced blood loss, reduced postoperative pain, faster postoperative recovery, shorter hospital stay, lower morbidity and better outcomes compared to open surgery. The most common robotic procedures in urology are radical prostatectomies. In UHC Zagreb, since November 2019 until now, there have been more than 180 robotic assisted radical prostatectomies (RALP) using Senhance robotic system performed. As a procedure with many possible complications, it represents a challenge for anaesthesiologist. Some of the problems the anaesthesiologists have to face are related to limited patient access, possible difficulties connected with positioning, pneumoperitoneum, subcutaneous emphysema, possible airway oedema. Pneumoperitoneum has impact on almost every system: cardiovascular, renal, respiratory, gastrointestinal and other. Detailed understanding of physiological changes of RALP, with intraoperative impact on nearly every body system is ultimate. Careful preoperative evaluation and intraoperative conduction minimize the risk of complications, and help patients to reach full recovery in a very short time. Excellent outcomes are the result of individualized approach to the patient and good communication between team members.

Validation of esophageal Doppler for noninvasive hemodynamic monitoring under pneumoperitoneum

Abstract: Esophageal Doppler monitoring is a valid noninvasive method of estimating cardiac output at baseline and during pneumoperitoneum in a porcine model. Corrected flow time did not correlate with other estimates of preload at baseline or during pneumoperitoneum.
