How does midazolam affect the heart?

Midazolam enhances the dominance of sympathetic activity, which is associated with increased HR and decreased BP. These differences in effects on cardiac autonomic nervous system activity during conscious sedation are important in patients at risk of cardiovascular complications.

Does midazolam affect blood pressure?

Midazolam does not affect BP or HR.

Can midazolam cause arrhythmia?

The incidence of dysrhythmias during surgery was not significantly different during the two procedures. However prior to surgery, 25% of the patients had dysrhythmias during sedation with midazolam. The majority of dysrhythmias were infrequent unifocal ventricular ectopics.

Can midazolam cause tachycardia?

Respiratory: Laryngospasm, bronchospasm, dyspnea, hyperventilation, wheezing, shallow respirations, airway obstruction, tachypnea. Cardiovascular: Bigeminy, premature ventricular contractions, vasovagal episode, bradycardia, tachycardia, nodal rhythm.

Can midazolam cause hypotension?

With the accumulation of experience, doctors found out that the recommended dose (0.2–0.3 mg/kg) of midazolam may cause significant hypotension. Previous study has shown that it is associated with a dose related hypotension.

Does midazolam slow heart rate?

Under spinal anaesthesia, intravenous midazolam decreases blood pressure and heart rate (HR)’. However, the effects of midazolam on the cardiac autonomic nervous system, which has a vital role in neural control for maintaining cardio- vascular stability, have not been well studied.

Does midazolam affect breathing?

IMPORTANT WARNING: has been expanded. Midazolam injection may cause serious or life-threatening breathing problems such as shallow, slowed, or temporarily stopped breathing that may lead to permanent brain injury or death.

Does midazolam have any effect on cardiovascular parameters?

No significant effect on cardiovascular parameters could be observed with administration of midazolam, but a modest (14.3%) isoflurane-sparing effect was detected.

Does midazolam cause pharyngeal dysfunction?

Midazolam markedly increased incidence of pharyngeal dysfunction from 16 to 48% and 59%. Morphine prolonged apnea before swallowing, and midazolam increased the number of swallows followed by inspiration.

Is midazolam a benzodiazepine?

Midazolam is an imidazobenzdiazepine that acts as an agonist on the GABA A receptor. Similar to other benzodiazepine agonists it induces anticonvulsant, anxiolytic, sedative/hypnotic, amnesic and centrally mediated muscle relaxant effects [ 15 ].

What are the side effects of midazolam for sleep apnea?

Commonly reported side effects of midazolam include: apnea and bradypnea. Other side effects include: variable blood pressure.
