Abstract
Objective
This study aimed to investigate the effects of neuromuscular blocking drugs on the
viability of human umbilical vein endothelial cells (HUVECs) and to investigate whether
they cause vascular complications due to cell proliferation.
Methods
HUVECs were cultivated with 5% CO2 at 37°C in a predefined supplemented
medium over 7 days until confluence of cell monolayers. Assays were conducted during the
exponential growth phase. Suxamethonium chloride, vecuronium bromide, atracurium
besylate, and rocuronium bromide were used at concentrations of 10–5,
10–6, and 10–7 M in proliferation assays in which cells were
incubated with these drugs for 24, 48, and 72 hours. All experiments were performed in
four replicates.
Results
The neuromuscular blocking drugs used had comparable effects on the survivability of
HUVECs. Overall, no significant difference was observed in the survivability of HUVECs
in a dose-dependent manner after exposure to the study drugs. However, some significant
differences in the viability of HUVECs were found among the different measurement
times.
Conclusions
The findings of the current study support the safety of the studied neuromuscular
blocking drugs in clinically relevant concentrations regarding their effects on
endothelial cell proliferation.
