Randomized Controlled Trial Comparative Study Clinical Trial
Non-invasive measurement of cardiac output during induction of anaesthesia and tracheal intubation: thiopentone and propofol compared.
We have investigated the haemodynamic changes in response to induction of anaesthesia and tracheal intubation in patients who received either thiopentone 5 mg kg-1 or propofol 3 mg kg-1 followed by atracurium 0.5 mg kg-1 and fentanyl 1.5 micrograms kg-1. Anaesthesia was maintained with 0.6% enflurane and 50% nitrous oxide in oxygen with assisted ventilation. Cardiac output and heart rate (HR) were monitored continuously with a transthoracic impedence monitor. ⋯ Both variables increased from preinduction values 1 min after tracheal intubation (P less than 0.001). In contrast, both MAP and SVR decreased after induction in the propofol group (P less than 0.001) and did not differ from preinduction values 1 min after tracheal intubation. MAP and SVR were greater in the thiopentone group compared with the propofol group after induction and tracheal intubation (P less than 0.01).

Randomized Controlled Trial Clinical Trial
Intraocular pressure and hemodynamic changes following tracheal intubation in children.
To determine the optimal time in which to make intraocular pressure (IOP) measurements in children following tracheal intubation. ⋯ We recommend that IOP be measured only after HR and MAP have returned to preintubation levels in children who have undergone tracheal intubation during halothane and N2O anesthesia.

Review Case Reports
Postextubation laryngeal spasm in an unanesthetized patient with Parkinson's disease.
We present a patient with Parkinson's disease who experienced laryngeal spasm after tracheal extubation without having been anesthetized. This patient's trachea was intubated because of respiratory arrest. We postulate that her postextubation laryngospasm was related to Parkinson's disease.
