Preoperative “R wave amplitude variation” on electrocardiogram predicts severe hypovolemia
Annals of Cardiac Anaesthesia, 2019 Preoperative fasting is essential to prevent aspiration and associated complications. However, quite often patients end up fasting for 12 h or more due to changes in the operating room schedules, delays, and postponements.

Different perspectives for monitoring nociception during general anesthesia [PDF]
Korean Journal of Anesthesiology, 2022 Safe anesthesia is achieved using objective methods that estimate the patient’s state during different phases of surgery. A patient’s state under anesthesia is characterized by three major aspects, which are linked to the main effects produced by each of

Assessment of the peripheral microcirculation using computer-assisted venous congestion plethysmography in post-traumatic complex regional pain syndrome type I [PDF]
, 2001 In complex regional pain syndrome type I (CRPS-I), edema of the affected limb is a common finding. Therefore, the changes in macro- and microcirculatory parameters were investigated to elucidate the underlying pathophysiology.

Plethysmographic Peripheral Perfusion Index: Could It Be a New Vital Sign?
Frontiers in Medicine, 2021 The plethysmographic peripheral perfusion index (PPI) is a very useful parameter with various emerging utilities in medical practice. The PPI represents the ratio between pulsatile and non-pulsatile portions in peripheral circulation and is mainly ...
