PURPOSE: Current analgesic strategies for propofol injection pain may cause adverse reactions during electroconvulsive therapy (ECT), such as shortening seizure duration. This study investigated whether dexmedetomidine could attenuate propofol injection pain in ECT. METHODS: Participants were randomly allocated to receive 0.2 μg/kg dexmedetomidine (Dex-0.2 group), 0.5 μg/kg dexmedetomidine (Dex-0.5 group) or saline (control group) prior to ECT. The composite pain scale and objective Surgical Pleth Index (SPI) were used to measure the intensity of injection pain, and the percentage of patients with pain score > 2 was the primary outcome...

BACKGROUND: Spinal anaesthesia carries a risk of hypotension. We hypothesized that pleth variability index and perfusion index would assess maternal volume status, and thus, allow identification of patients at higher risk of developing hypotension after spinal anaesthesia for caesarean delivery. METHODS: Fifty patients undergoing elective caesarean delivery were enrolled. All patients received spinal anaesthesia with 0.5% hyperbaric bupivacaine (10 mg) and fentanyl (10 mcg)...

Background: During laparoscopic surgery in paediatric patients, sudden hypotension may occur following peritoneal desufflation due to hypovolaemia or an acute increase in gastrointestinal venous capacitance by the release of intra-abdominal pressure. This study examined whether dynamic variables of fluid responsiveness during pneumoperitoneum can predict the occurrence of hypotension following desufflation. Methods: A total of 120 paediatric subjects were prospectively enrolled...

The aim was to assess the reproducibility of the Pleth Variability Index (PVI), developed for non-invasive monitoring of peripheral perfusion, in preterm neonates below 32 weeks of gestational age. Three PVI measurements were consecutively performed in stable, comfortable preterm neonates in the first 48 h of life. On each occasion, pulse oximeter sensors were attached to two different limbs for 5 min. Reproducibility was assessed with the intra-class correlation coefficient (ICC) and Bland-Altman analysis...

BACKGROUND: There is no well-recognized guideline for intraoperative fluid management in bariatric surgery. Goal-directed fluid therapy (GDFT) is a new concept of perioperative fluid management which was shown to improve patients' prognoses. Dynamic indicators may better predict fluid response compared to static indicators. In this study, we aimed to assess effects of administering GDFT protocol via Pleth Variability Index (PVI) in morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass (RYGB) surgery...

BACKGROUND: Delayed graft function (DGF) is an early postoperative complication of kidney transplantation (KT) predisposing to acute rejection and lower graft survival. Intraoperative arterial hypotension and hypovolemia are associated with DGF. Central venous pressure (CVP) is used to estimate volemia but its reliability has been criticized. Pleth variability index (PVI) is a hemodynamic parameter predicting fluid responsiveness. The aim of this study was to examine the relationship between intraoperative PVI and CVP values and the occurrence of DGF...

OBJECTIVES: Patients with obstructive airway disease have varying degrees of pulsus paradoxus that correlate with illness severity. Pulsus paradoxus can be measured using plethysmography. We investigated whether plethysmograph (pleth) variability on admission to the pediatric emergency department (ED) could predict patient disposition. We hypothesized that patients with a larger pleth variability would have a higher likelihood of being admitted to a general pediatrics unit or the intensive care unit (ICU)...

STUDY OBJECTIVE: Hypertension or hypotension in patients receiving continuous infusions of dexmedetomidine (DEX) is often due to changes in vascular resistance caused by α2 receptor stimulation. We investigated whether baseline perfusion index (PI) and pleth variability index (PVI), derived from pulse oximetry readings, could predict DEX-induced changes in the hemodynamic status in spontaneously breathing patients. DESIGN: Observational study. SETTING: Operating room...

BACKGROUND: The surgical pleth index (SPI) is a measurement of intraoperative nociception. Evidence of its usability in children is limited. Given that the autonomic nervous system is still developing during the first years of life, the performance of the SPI on small children cannot be concluded from studies carried out in older age groups. METHODS: Thirty children aged <2 yr, planned for elective open inguinal hernia repair or open correction of undescended testicle, were recruited...

Fluid management is challenging and still remains controversial in orthotopic liver transplantation (OLT). The pleth variability index (PVI) has been shown to be a reliable predictor of fluid responsiveness of perioperative and critically ill patients; however, it has not been evaluated in OLT. This study was designed to examine whether the PVI can reliably predict fluid responsiveness in OLT and to compare PVI with other hemodynamic indexes that are measured using the PiCCO2 monitoring system. Twenty-five patients were enrolled in this study...

BACKGROUND: Accurate estimation of cardiac preload during liver transplantation is essential. The right ventricular end-diastolic volume index (RVEDVI) is recognized as a good preload indicator in patients undergoing liver transplantation. Recently, dynamic variation parameters including pleth variability index (PVI) have been used as predictors of fluid responsiveness. However, the correlation between PVI and preload status has not been well studied. We evaluated the relationship between PVI and RVEDVI during liver transplantation...

BACKGROUND: The nociception level (NoL) index is an index of nociception based on nonlinear combination of heart rate, heart rate variability, photoplethysmograph wave amplitude, skin conductance, skin conductance fluctuations, and their time derivatives. The authors evaluated the abilities of the NoL index and other measures of nociception to discriminate between noxious and nonnoxious stimuli, to progressively respond to graded stimuli, and to respond to opioid administration. METHODS: Intraoperative NoL was compared to heart rate, pulse plethysmograph amplitude, noninvasive blood pressure, and the surgical pleth index around five specific stimuli: tetanic stimulation with and without fentanyl analgesia, intubation, first incision/trocar insertion, and a nonnoxious period...

BACKGROUND: The probability to tolerate laryngoscopy (PTOL) and its derivative, the noxious stimulation response index (NSRI), have been proposed as measures of potency of a propofol-remifentanil drug combination. This study aims at developing a triple drug interaction model to estimate the combined potency of sevoflurane, propofol, and remifentanil in terms of PTOL. We compare the predictive performance of PTOL and the NSRI with various anaesthetic depth monitors. METHODS: Data from three previous studies (n=120) were pooled and reanalysed...

OBJECTIVE: We assessed the utility of the pulse oximeter perfusion index (PI) in maternal monitoring immediately after delivery. METHODS: We examined 30 pregnant women without any complications using the Rad7 device at delivery. The correlations between heart rate (HR), systolic blood pressure (BP), oxygen saturation SpO2, PI, Pleth variability index (PVI), shock index and blood loss were assessed. RESULTS: Blood loss at 20-min postpartum was not correlated with the difference in heart rate, systolic BP, SpO2, shock index or PVI taken immediately after delivery and at 20-min postpartum, but showed a strong negative correlation with the difference in the PI taken immediately after delivery and at 20-min postpartum (r = -0...
