Abstract

This study was performed to examine the safety of Aldrete Scoring system and reliability of 8 objective non-invasive methods in evaluation of post-anesthesia recovery. Aldrete Score(AS ) and maximum inspiratory force(MIF), hand muscle grip
power(HMGP),
respiratory frequency(RF), tidal volume(VT), arterial oxygen saturation(SaO2), systolic blood pressure(sBP), heart rate(HR), and orientation were measured at pre-anesthesia period, arrival to recovery room and AS 10 in 137 patients during 3
months
in
1993 at Yongsan hospital, College of medicine, Chungang University. Data obtained by objective non-invasive methods at AS 10 were compared with their relevant recovery criteria of objective non-invasive methods by using t-test.
@ES The results were as follows:
@EN 1. MIF of 63 patients at AS 10 was below the discharge criteria from recovery room(DCrm), but the mean MIF(-34.6±23.4cmH2O) was above the DCrm. Women, aging over 30 years or weighing below 60 kg, were significant difference among those whose
MIF
was below the DCrm(P<0.05).
2. VT of 118 patients at AS 10 was below their DCrm and the mean VT(3.5±1.4ml/kg) was significant difference below the DCrm(P<0.01). Women were more highly distributed among those who VT was below the DCrm.
3. SaO2 of 2 patients at AS 10 was below their Dcrm but the mean SaO2(98.0±0.8%) was above the DCrm.
4. HMGP and orientation at AS 10 were above their DCrm.
5. RF, systolic blood pressure and pulse rate at AS 10 were within the range of their DCrm.
6. VT, MIF and SaO2 of some patients complained the general malaise or respiratory difficulty during postanesthesia 24 hours were less than DCrm.
Above results showed that AS 10 was not enough to fulfil the recovery discharge criteria of MIF,
VT and SaO2. Hence some objective non-invasive monitorings such as SaO2, MIF and VT need to be adopted to secure the safe recovery in the recovery room.
