Study summary

The Dreams study is an observational study aimed at evaluating the incidence of connected awareness after intubation, intraoperative explicit and implicit memorization, and postoperative well-being in patients receiving general anesthesia without opioids.

Outcomes

The primary objective is the evaluation of the incidence of connected consciousness after induction of general anesthesia without opioids and intubation. The secondary objectives are:

  • Implicit and explicit memorization after intubation and during the procedure
  • Post-operative well-being Pain in the recovery room and in the room, assessed by VAS;
  • Total consumption of analgesics (paracetamol, diclofenac, tramadol): data collected during discharge
  • Level of satisfaction, assessed using the EVAN scale
  • Duration of hospitalization
  • Estimated first mobilization

Study population

We study patients 18-75 aged undergoing laparoscopic robotic surgery ( prostatectomy, hysterectomy, colectomy) with an ASA status from 1 to 3.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • laparoscopic robotic surgery
  • 1 to 3

Exclusion criteria

Exclusion Criteria:

  • neurological and psychiatric diseases
  • reflect memory disorders
  • head trauma
  • hearing disorders
  • past or current use of medications affecting the central nervous system.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

What researchers measure

Primary outcomes

  1. Implicite memorization incidence

    Through the isolated forearm technique and with the capacity of patients to recognize post operatively sounds that they have listened during the anesthesia, we evaluate the incidence of implicite memorization

    Time frame: From the operating room to one week after surgery

Secondary outcomes

  1. explicite memorization

    Through the modified brice questionnaire, we assess the incidence of explicite memorization

    Time frame: From the operating room to one week after surgery

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 12, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
