Continuous versus intermittent noninvasive blood pressure monitoring during beach chair position for shoulder surgery: A randomised controlled trial

Continuous noninvasive arterial pressure monitoring is not effective in reducing the amount of intra-operative hypotension during shoulder surgery performed in the beach chair position compared to intermittent oscillometric monitoring.
Study context
- Population
- Patients scheduled for arthroscopic shoulder surgery in beach chair position under brachial plexus block plus GA, single orthopaedic theatre, Rome, Italy
- Participants
- 60 patients
- Comparison

- Finger-cuffn = 30
- Controln = 30reference
- Primary endpoint
- Time-weighted average MAP under the threshold of 65 mmHg
- Follow-up
- During surgery

Primary result
As reported in the abstract
Hodges-Lehman estimator
−0.24 mmHg
95% CI - 0.75 to 0.07
P = 0.137
By group
Secondary outcomes
| Outcome | P value |
|---|---|
| Severe hypotensive events (MAP <50 mmHg) | P = 0.017 |
Severe hypotensive events (MAP <50 mmHg)
- No difference detected between the two groups
Cerebral tissue oxygen saturation
- Stable for most of the monitoring period; absolute values <60% and relative values <10% of baseline uncommon in both groups
Correlation of tissue oxygen saturation with MAP
- Positive correlation, r
- 0.298 (95% CI 0.283 to 0.312, P < 0.001)
