Comparison between Colloid Preload and Coload in Bone Cement Implantation Syndrome under Spinal Anesthesia: A Randomized Controlled Trial.

BACKGROUND

Bone cement implantation syndrome (BCIS) is characterized by hypoxia hypotension cardiac arrest. There is not any research that investigated the hemodynamic effects of colloid use during and before cement implantation regarding BCIS development.

AIMS: We aimed to compare the effects of colloid preloading before or coloading simultaneously at cement implantation on BCIS development and hemodynamic parameters in patients who underwent total knee arthroplasty.

SETTINGS AND

DESIGN

This is a prospective, randomized, clinical trial with the participation of 109 patients over 60 years of age and patients physical status American Society of Anesthesiologists Classes I and II to undergo knee surgery. The patients were administered spinal anesthesia, divided into three groups.

SUBJECTS AND

METHODS

The patients in Group I were infused 8 mL/kg hydroxyethyl starch (130/0.4) 20 min before the cement implantation, those in Group II were infused the same simultaneously during cement implantation. Group III was infused 8 mL/kg/h sodium chloride during the anesthesia management. Hemodynamic parameters of the patients were recorded at before and after cement implantation and once the tourniquet was removed.

STATISTICAL ANALYSIS USED: The descriptive statistics were presented as the mean ± standard deviation for normally distributed variables, as the median for nonnormally distributed variables, and as the number of cases and (%) for nominal variables. Pearson's Chi-square test and Fisher's exact test were used in the analysis of categorical variables.

RESULTS

Compared to the control group, Groups I and II were hemodynamically more stable. The development of moderate hypoxia during cement implantation was significantly different between the study groups (P < 0.05).

CONCLUSIONS

We suggest that avoiding intravascular volume depletion by using the colloids, particularly in elderly patients, is important for preventing from the BCIS.
