Comparison between two methods of measuring cardiac output: misleading analyses?

Intraoperative awareness and the isolated forearm technique Sir,—The correspondence columns of The Times newspaper (April 8, 18, 1995) is not the forum to air the obviously diverging views on the use of the isolated forearm technique (IFT) to detect intraoperative awakening and the significance of this level of consciousness to anaesthetic practice. We were astounded to read that the IFT " has ...

NEUROSCIENCES AND NEUROANAESTHESIA Surveyon the adequacyof depth of anaesthesia with bispectral index and isolated forearm technique in elective Caesarean section under general anaesthesia with sevoflurane

Editor’s key points † Bispectral index (BIS) monitoring is commonly used to monitor depth of anaesthesia. † The authors studied parturients in whom standard techniques were used for general anaesthesia for Caesarean section. † The isolated forearm test was used to study the ability of the BIS to detect consciousness. † BIS values below 60 were commonly associated with IFT responses, particularl...

Interpretations of responses using the isolated forearm technique in general anaesthesia: a debate.

The isolated forearm technique (IFT) enables an otherwise paralysed patient to communicate awareness to the anaesthetist. We present a debate that focuses on how best to interpret IFT responses. On one side, Pandit argues that there is a range of response types from none through to movement initiated by the patient to alert the researcher. He also presents a de novo numerical scale by which IFT...

NAP5 and isolated forearm technique: reply.

not suitable for deployment. The encouragement in the NAP5 report of IFT training and its apparent elevation to equal status with pEEG, may lead to wellmeaning but potentially harmful clinical experimentation, with unknown consequences for patients. Although a tourniquetmay be safely inflated for a limited period during arm surgery, failure to deflate an IFT cuff might eventually lead to seriou...

Absence of memory for intraoperative information during surgery under adequate general anaesthesia.

Using the isolated forearm technique (IFT), we wished to determine if patients known to be unresponsive to commands during general anaesthesia with nitrous oxide, halothane and neuromuscular blocking agents had any evidence of explicit or implicit recall. Two groups of women, studied in a single-blind sequential block design, heard different tapes, either a command and information tape (n = 34)...
