Novel Perioperative Utilities of the Newer Co-Oximetery Parameters: A Practical Review

  title={Novel Perioperative Utilities of the Newer Co-Oximetery Parameters: A Practical Review},
  author={Shagun B. Shah and Uma Hariharan and Bhargava Ak and Rajiv A. Gandhi},
The radical-7 signal extraction technology (SET) Masimo pulse co-oximeter has raised the technology bar with non invasive and continuous measurement of haemoglobin, carboxy haemoglobin and methemoglobin and newer parameters like perfusion index, pleth variability index and acoustic respiratory index. These can be measured intraoperatively and in the critical care setup. We reviewed the current literature for the clinical utility of these parameters and to what extent this technology has… Expand
Capstesia™: The smart hemodynamic monitor!
Capstesia™ can be of immense utility in patient care and monitoring both in the operating room and the intensive care units and it's usage, present limitations and future possibilities are presented. Expand
Capstesia TM : The smart hemodynamic monitor !
Advanced hemodynamic monitoring can be both time and cost consuming in the perioperative period. Smartphones which have become an important part of our lives, can help circumvent this difficultExpand
Clinical pearls in anesthesia for excision and reconstructive surgery for cauliflower carcinoma on psoriatic plaques
Meticulous preoperative evaluation and planning is essential in psoriasis patients presenting for surgery as the airway and axial skeleton may both be involved in addition to extensive integumentaryExpand
Perfusion Index as a Predictor of Hypotension Following Spinal Anesthesia in Lower Abdominal Surgery
Ab s t r Ac t Background and aim: Subarachnoid block (SAB) is a gold standard anesthetic technique for lower abdominal surgeries. Hypotension is a very common observation following a SAB. PerfusionExpand


Respiratory Variation in Pulse Pressure and Plethysmographic Waveforms: Intraoperative Applicability in a North American Academic Center
Dynamic variables are the best predictors of fluid responsiveness in patients under general anesthesia and mechanical ventilation; namely, respiratory variations in pulse pressure and in the plethysmographic waveform and their intraoperative applicability is evaluated. Expand
Accuracy of the pleth variability index to predict fluid responsiveness depends on the perfusion index
Whether the predictive power of PVI depends on different values of PI, a variable based on the calculation of changes in the perfusion index, is examined. Expand
The pulse oximeter perfusion index as a predictor for high illness severity in neonates
Predictive accuracy for identifying newborns with higher severity for different cut-off values of PI, SpO2, and pulse rate was calculated using receiver operating characteristic (ROC) curve. Expand
Pulse oximeter perfusion index as an early indicator of sympathectomy after epidural anesthesia
It is hypothesized that pulse oximeter PI provides an earlier and clearer indication of sympathectomy following epidural anesthesia than skin temperature and arterial pressure. Expand
Respiratory variations in pulse oximetry plethysmographic waveform amplitude to predict fluid responsiveness in the operating room.
DeltaPOP can predict fluid responsiveness noninvasively in mechanically ventilated patients during general anesthesia and this index has potential clinical applications. Expand
Pleth variability index to monitor the respiratory variations in the pulse oximeter plethysmographic waveform amplitude and predict fluid responsiveness in the operating theatre.
PVI, an automatic and continuous monitor of DeltaPOP, can predict fluid responsiveness non-invasively in mechanically ventilated patients during general anaesthesia and has potential clinical applications. Expand
New generation pulse oximetry in the assessment of peripheral perfusion during general anaesthesia - a comparison between propofol and desflurane.
Both intravenous propofol/remifentanil and desflurane/fentanyl general anaesthesia increase peripheral perfusion, and an increase in end-tidal desFLurane concentration raises peripheral perfusions. Expand
Perfusion Index-A valuable tool to assess changes in peripheral perfusion caused by sevoflurane?
The hypothesis that the perfusion index, which is derived from absorption o f two infrared wave lengths, correlates better with endtidal sevoflurane concentration than the forearm-fingertip temperature gradient is tested. Expand
Oximetry-derived perfusion index for intraoperative identification of successful thoracic sympathectomy.
In patients with hyperhidrosis of the upper extremity, the intraoperative PI derived from pulse oximetry is an additional indicator of successful thoracic sympathectomy. Expand
Perfusion index versus non-invasive hemodynamic parameters during insertion of i-gel, classic laryngeal mask airway and endotracheal tube
PI is a reliable and easier alternative to conventional haemodynamic criteria for detection of stress response to insertion of i-gel, LMA and ET during propofol fentanyl isoflurane anaesthesia in adult patients. Expand
