Memory During Anesthesia: the Role of Stress Hormones

2014-08-27 03:12:49 | BioPortfolio


1. To investigate whether the auditory stimulation causes changes in hormones levels (cortisol+prolactin) during general anesthesia.

2. To determine if there is a correlation between hormones levels (cortisol+prolactin) and dreams recall.

3. To investigate whether, in patients receiving auditory stimulation, there is a correlation between hormones levels (cortisol+prolactin), serum remifentanil concentration and detection of implicit memory.

4. To investigate the presence of primary auditory cortex activation (temporal lobe) in patients with implicit memory and in those with dreams recall using the EEG-ERP 128 channels GES300 EGI system.


Patients from group A, during maintenance of anesthesia, at the time of trocar insertion, will listen (via MP3) a piece of one of two stories, "Puss in Boots" and "Pinocchio", each followed by four keywords. In group B, patients will be isolated from the sounds of the operating room using specific headphones.

Medical and Biotech [MESH] Definitions

Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.

Procedures that avoid use of open invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device. With the reduced trauma associated with minimally invasive surgery, long hospital stays may be reduced with increased rates of short stay or day surgery.

Excision of the gallbladder through an abdominal incision using a laparoscope.

Surgery which could be postponed or not done at all without danger to the patient. Elective surgery includes procedures to correct non-life-threatening medical problems as well as to alleviate conditions causing psychological stress or other potential risk to patients, e.g., cosmetic or contraceptive surgery.
