Less invasive measuring procedures for hemodynamic status and function are increasingly being used. Surgical patients are frequently undifferentiated, need accurate risk assessment and stratification, while their need for diagnosis and therapy is often time-critical. ⋯ Pulmonary artery catheters, transesophageal echocardiography, pressure pulse waveform analysis, and other less invasive monitoring techniques all are potentially effective for diagnosis and hemodynamic monitoring. This article provides information on the usefulness and limitations of recent circulatory monitoring procedures.

It is more than 60 years since averaged somatosensory evoked potentials (SEPs) were devised. During this period, other evoked potentials including spinal cord evoked potentials and motor evoked potentials (MEPs) were developed. ⋯ The combination of these evoked potentials (multimodality monitoring) has been demonstrated to be sensitive and specific for detecting intraoperative neurologic injury during spine surgery. Although there is still a low level of evidence that intraoperative evoked potentials reduce the rate of new or worsened perioperative neurologic deficits, it is recommended to monitor MEP for thoracoabdominal aortic surgery and multimodal evoked potentials including at least spinal cord evoked potentials and MEP for spine surgery, when the spinal cord is considered to be at risk.

Randomized Controlled Trial
[Effectiveness of gum elastic bougie for tracheal intubation with Airtraq optical laryngoscope].
Although Airtraq (ATQ) is well accepted as a useful device for tracheal intubation especially in cases of difficult airway management, we sometimes encounter difficulty in insertion of a tracheal tube along the blade of ATQ across the vocal cord in spite of ATQ assistance. Gum Elastic Bougie (GEB) is well known as a practical device for intubation assistance with Macintosh laryngoscope. We studied the efficacy of GEB for intubation with ATQ. ⋯ For the people with less experience of intubation, GEB is useful assistance for intubation with ATQ. It was concluded that the combined use of ATQ and GEB is a simple and effective process for ordinary doctors or paramedics.

Randomized Controlled Trial
[Effect of amino acid and glucose infusion on perioperative body temperature and postoperative infection in patients undergoing total knee arthroplasty].
We investigated whether the perioperative amino acid infusion with glucose is effective for preventing perioperative hypothermia and postoperative infection in patients undregoing total knee arthroplasty (TKA). ⋯ These results suggest that in patients undergoing TKA receiveing amino acid infusion perioperatively, thermogenic effect and prevention of postoperative infection are similar whether exogenous glucose is infused or not.
