The new recovery position, a cautionary tale

R Fulstow1, G B Smith

  • 1Portsmouth Hospital NHS Trust, Hampshire, UK.

Resuscitation
|August 1, 1993

Summary

The modified recovery position recommended in 1992 may obstruct venous return in the dependent arm. Researchers found 67% of volunteers experienced obstruction in the new position, compared to none in the semi-prone recovery position.

Area of Science:

  • Emergency Medicine
  • Cardiovascular Physiology

Background:

  • The European Resuscitation Council updated recovery position guidelines in 1992.
  • Anecdotal evidence suggested the modified recovery position might impede venous return in the dependent arm.

Purpose of the Study:

  • To evaluate the impact of the modified recovery position on venous return and limb perfusion.
  • To compare the safety of the modified recovery position with the traditional semi-prone recovery position.

Main Methods:

  • A small study involving six healthy adult volunteers.
  • Measurements included digital temperature, plethysmographic waveform, and transcutaneous oxygen saturation.
  • Data collected in both the modified and semi-prone recovery positions.

Main Results:

  • 67% of participants showed signs of venous or arterial obstruction in the modified recovery position.
  • No obstruction was observed in the semi-prone recovery position.
  • The modified position potentially compromises circulation in the dependent limb.

Conclusions:

  • The modified recovery position may lead to circulatory compromise.
  • Reconsideration of the semi-prone recovery position is suggested.
  • If using the modified position, close monitoring of limb perfusion and venous drainage is essential.
