Laryngoscopy grades might influence the cardiovascular response

Double-lumen tube intubation using video laryngoscopy causes a milder cardiovascular response compared to classic direct laryngoscopy

OBJECTIVE To determine whether there is a clinically relevant difference between the circulatory responses to double-lumen tube intubation (DLTI) with the GlideScope video laryngoscope versus the Macintosh direct laryngoscope. METHODS Eighty adult patients requiring double-lumen tubes for thoracic surgery were randomly and equally allocated to either a Macintosh direct laryngoscope group (DL ...

Comparison of different doses of remifentanil on the cardiovascular response to laryngoscopy and tracheal intubation.

We have compared three bolus and infusion regimens of remifentanil on the cardiovascular response to laryngoscopy and orotracheal intubation in three groups of 20 ASA I-II female patients, in a randomized, double-blind study. Patients in group 1 received glycopyrolate 200 micrograms i.v. followed by a bolus dose of remifentanil 1 microgram kg-1 over 30 s and an infusion of remifentanil at a rat...

How nutrition might modify the possible effects of air pollution on cardiovascular diseases risk?

How climate change might influence the starvation-predation risk trade-off response.

Climate change within the UK will affect winter starvation risk because higher temperatures reduce energy budgets and are likely to increase the quality of the foraging environment. Mass regulation in birds is a consequence of the starvation-predation risk trade-off: decreasing starvation risk because of climate change should decrease mass, but this will be countered by the effects of predation...

Effect of nifedipine on cardiovascular responses to laryngoscopy and intubation.

The efficacy of sublingual nifedipine in attenuating the pressor responses to laryngoscopy and intubation was studied in 40 patients undergoing elective surgery. Anaesthesia was induced with thiopentone 5.5 mg kg-1 i.v. and tracheal intubation was facilitated with suxamethonium 1.5 mg kg-1 i.v. Patients were allocated randomly to receive sublingual nifedipine 10 mg or placebo capsules 10 min be...
