Randomized Controlled Trial Comparative Study Clinical Trial
The effects of forced-air warming on postbypass central and skin temperatures and shivering activity.
To test the hypothesis that forced-air skin-surface warming used prophylactically after hypothermic cardiopulmonary bypass (CPB) would: (1) decrease the incidence and severity of postbypass shivering, (2) rapidly increase skin-surface temperatures when compared with standard warmed cotton blankets, and (3) not contribute to excessive central temperature elevation. ⋯ Convection warming, when compared with conductive warming with cotton blankets, limited the incidence, magnitude, and duration of shivering following hypothermic cardiac surgery. This suggests an important role of cutaneous thermal input in the mediation of the shivering response. The central tissue compartment is buffered from the effects of skin-surface warming and, thus, forced-air therapy will not lead to excessive central temperature elevation in this patient population when compared with cotton blanket rewarming.

Incidence and risk factors of guidewire-induced arrhythmia during internal jugular venous catheterization: comparison of marked and plain J-wires.
To compare the incidence and risk factors of guidewire-induced arrhythmia (GIA) during internal jugular venous catheterization (IJV). ⋯ Limiting the length of the guidewire insertion to less than or equal to 20 cm for right IJV catheterization by using a marked J-wire will reduce the incidence of GIA. We recommend the use of a marked J-wire for IJV catheterization.

Randomized Controlled Trial Clinical Trial
The efficacy of single-dose aprotinin 2 million KIU in reducing blood loss and its impact on the incidence of deep venous thrombosis in patients undergoing total hip replacement surgery.
To evaluate the efficacy of a 2 million KIU single dose of aprotinin on blood loss, transfusion requirements, and incidence of deep venous thrombosis (DVT) in patients undergoing total hip replacement surgery. ⋯ A single 2 million KIU bolus dose of aprotinin does not reduce perioperative blood loss or transfusion requirements. Aprotinin therapy, when used in conjunction with other antithrombotic therapies, does not increase the incidence of DVT after major orthopedic surgery.

Effect of varying intravenous patient-controlled analgesia dose and lockout interval while maintaining a constant hourly maximum dose.
To investigate the effect on the use of intravenous patient-controlled analgesia (PCA) of varying the dose (D) and lockout interval (LI) while keeping the hourly maximum dose constant. ⋯ The use of 1.0 mg with a 6-minute lockout may represent appropriate dose titration because this group obtained equivalent analgesia, morphine use, and side effects as the two larger dose and lockout groups. However, the increased number of PCA attempts and missed attempts may reflect lower satisfaction with PCA therapy.
