Final answer:
The POISE trial on beta blockers showed mixed results in terms of outcomes for patients undergoing non-cardiac surgery.
Step-by-step explanation:
The POISE trial is a clinical study that investigated the use of beta blockers in patients undergoing non-cardiac surgery. The trial evaluated the impact of beta blockers on major cardiovascular events, such as heart attacks and strokes, in this patient population. The outcome of the trial showed that while beta blockers reduced the risk of certain cardiovascular events, they also increased the risk of other complications, such as low blood pressure and slow heart rate.
Therefore, the overall outcome of the POISE trial on beta blockers was a mixed one, with both positive and negative effects observed. This highlights the importance of carefully weighing the risks and benefits when considering the use of beta blockers in surgical patients.
