Heat and Moisture Exchanger and Low-flow Gas
The Effects of a Heat and Moisture Exchanger on Temperature and Humidity in Low -Flow Anesthesia Workstation

The aim of the present study was to measure the inspired gas temperature and humidity of the anesthetic circuit in the Dräger Primus machine and esophageal temperature with or without and heat and moisture exchanger (HME) and low-flow gas during anesthesia in patients submitted to gynecological surgeries.

Probability Sample

Thirty adult patients scheduled to gynecologic surgeries were randomly assigned in two groups to received fresh gas flow of 1 l.min-1 with or without in circle anesthesia system. Relative humidity, absolute humidity, temperature of gases and esophageal temperature were measured at 15 min (T0)after respiratory circuit installation and then every 30 min up to 120 min afterwards.

  • Gynecological Surgery
  • General Anesthesia
Not Provided
  • Heat moisture exchanger (HME)
    This group was submitted to general anesthesia with low flow gas and heat moisture exchanger
  • Low flow gas (LFG)
    This group was submitted to general anesthesia with only low flow gas
  • Humidity of the respiration

    Heat and moisture group:

    The first group (G1)will be submitted to low flow gas anesthesia and heat and moisture exchanger (HME)

    Control group:

    The second group(G2)Will be submitted to low flow gas anesthesia

  • HME and LFG
