Traditional hemodynamic monitors such as pulmonary artery and central venous catheters provide continuous data and secure intravenous access, but their diagnostic efficacy has been criticized. Dynamic arterial waveform monitoring is promising, but studies suggest it is reliable only within narrow ventilation and rhythm parameters. ⋯ Recent efficacy data, along with other important clinical findings, are reviewed with regard to invasive monitors. We caution against over-generalizing from existing studies, and provide guidance for clinicians wishing to target monitoring techniques for appropriate patients.

To investigate whether the phase of menstrual cycle influences the incidence of postoperative nausea and vomiting (PONV) in women undergoing general anesthesia for elective laparoscopic gynecological surgery. ⋯ Patients in the luteal phase of their menstrual cycle may have a decreased risk of PONV after laparoscopic gynecological surgery in the early postoperative period.

To investigate changes in stroke volume variation (SVV) by both induced hypertension (pressor test) and hypotension (depressor test), and also by induced hypotensive anesthesia in patients with good cardiac function. ⋯ SVV does not misinterpret preload dependency assessment of patients receiving medications to increase or to lower blood pressure.

To determine the incidence and contributing factors of complications for patients receiving regional ophthalmic anesthesia. ⋯ Peribulbar block complications were rare. In this series, experience of caregivers and axial and needle length were not contributing factors.
