In vitro assessment of human chondrocyte viability after treatment with local anaesthetic, magnesium sulphate or normal saline.

Summary of "In vitro assessment of human chondrocyte viability after treatment with local anaesthetic, magnesium sulphate or normal saline."

Local anaesthetic agents are often used as an intra-articular analgesic following arthroscopic procedures. However, there is increasing evidence of a potential toxic effect to chondrocytes within the articular cartilage. The aim of this study was to compare the effect on human chondrocyte viability of treatment with bupivacaine, levobupivacaine and ropivacaine. The second aim was to compare the effect on chondrocyte viability of the local anaesthetics with magnesium, a potential alternative analgesic agent.
Chondrocytes were exposed to one of the local anaesthetic agents (levobupivacaine 0.13, 0.25, 0.5%; bupivacaine 0.13, 0.25, 0.5%; ropivacaine 0.19, 0.38, 0.75%), normal saline or 10% magnesium sulphate for 15 min. Cells exposed to cell culture media served as controls. Twenty-four hours after exposure, cell viability was assessed using the CellTiter 96(®) AQueous One Solution Cell Proliferation Assay.
There was no significant difference in chondrocyte viability after treatment with either normal saline or magnesium sulphate. With the exception of 0.13% levobupivacine, all local anaesthetic treatment showed significantly greater toxic effects than either normal saline or magnesium sulphate. Statistically significant dose-dependent responses of decreasing cell viability were found with increasing local anaesthetic concentration.
A dose-dependent reduction in chondrocyte viability after treatment with common local anaesthetic agents was confirmed. Local anaesthetic agents had a greater deleterious effect on chondrocytes than did 10% magnesium sulphate. These findings suggest the need for continuing caution with the use of intra-articular local anaesthetic. Magnesium sulphate is a potential alternative intra-articular analgesic agent.

Medical and Biotech [MESH] Definitions

The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.

The potential of the FETUS to survive outside the UTERUS after birth, natural or induced. Fetal viability depends largely on the FETAL ORGAN MATURITY, and environmental conditions.

A scale comprising 18 symptom constructs chosen to represent relatively independent dimensions of manifest psychopathology. The initial intended use was to provide more efficient assessment of treatment response in clinical psychopharmacology research; however, the scale was readily adapted to other uses.
