Supports limiting rotation to ≤45° in higher-BMI patients to minimize CCA contact; leaves open optimal angles in prospective cannulation trials.
Does the degree of head rotation affect the probability of internal jugular vein and common carotid artery contact during simulated cannulation in volunteers?
To optimize internal jugular vein cannulation and minimize carotid artery puncture risk, head rotation should be limited to 30° in obese patients, but can be up to 60° in non-obese patients.
Lieberman et al. (2004) studied this question.
