Key result
Continucath oxygen monitor correlates with conventional samples postoperatively but slow temperature response negates hypothermic use.
Why the study?
Does the Continucath intra-arterial oxygen monitor provide accurate measurements compared to conventional blood gas samples in patients undergoing hypothermic cardiac surgery?
Observational (n=9)
Does the Continucath intra-arterial oxygen monitor provide accurate measurements compared to conventional blood gas samples in patients undergoing hypothermic cardiac surgery?
The Continucath intra-arterial oxygen monitor shows good correlation with conventional blood gas samples postoperatively but is unsuitable during hypothermic surgery due to slow temperature response times.
An intra-arterial continuous display oxygen electrode for radial artery cannulation is now available in the UK. Nine catheters were used in patients during and after hypothermic cardiac surgery. Results obtained were compared with those from conventional intermittent blood gas samples. Slow temperature response times negate its use during hypothermic surgery. A good correlation was found during the postoperative period. Indications for its use are discussed.

Pfeifer et al. (1988) conducted an observational in Hypothermic cardiac surgery (n=9). Continucath intra-arterial oxygen monitor vs. Conventional intermittent blood gas samples was evaluated on Correlation with conventional intermittent blood gas samples. The Continucath intra-arterial oxygen monitor showed good correlation with conventional samples postoperatively, but slow temperature response times negate its use during hypothermic surgery.
