The relationship between symphysis-fundal height and intravenous ephedrine dose in spinal anesthesia for elective cesarean section.
A decreased lumbosacral subarachnoidal space volume is a major factor in the cephalad intrathecal spread of local anesthetics in term parturients and their subarachnoidal space is decreased due to the compressive effect of huge uteri. Therefore, they show a higher level of sensory block and hypotensive episodes. The purpose of this study is to investigate whether the symphysis-fundal height (SFH) correlates with the highest sensory level and the amount of ephedrine administered under spinal anesthesia. ⋯ In term parturients choosing elective cesarean section, the SFH is not correlated with the sensory level of spinal anesthesia, but is correlated with the amount of ephedrine administered during spinal anesthesia.

Recent advance in technology has developed a lot of new aspects of clinical monitoring. We can monitor sedation levels during anesthesia using various electroencephalographic (EEG) indices, while it is still not useful for anesthesia depth monitoring. Some attempts are made to monitor the changes in sympathetic nerve activity as one of the indicators of stress, pain/analgesia, or anesthesia. ⋯ Cerebral perfusion and metabolism are not ordinary monitored yet, but some studies show their usefulness in management of critically ill. This review introduces recent advances in various monitors used in anesthesia and critical care including some studies of the author, especially focused on EEG and cardiac output. However, the most important is that these new monitors are not almighty but should be used adequately in a limited situation where their meaning is confirmed.

The effect of perioperative esmolol infusion on the postoperative nausea, vomiting and pain after laparoscopic appendectomy.
Perioperative opioid administration results in postoperative nausea and vomiting (PONV) and acute opioid tolerance that manifests in increased postoperative pain. Esmolol is an ultra short acting cardioselective β1-adrenergic receptor antagonist, and it has been successfully used for perioperative sympatholysis and it reduces the opioid requirement during total intravenous anesthesia. We tested the hypothesis that perioperative esmolol administration results in decreased PONV and postoperative pain. ⋯ Perioperative esmolol administration contributes to the significant decrease in PONV and postoperative pain, and so this facilitates earlier discharge.

Vomiting after a pediatric adenotonsillectomy: comparison between propofol induced sevoflurane-nitrous oxide maintained anesthesia and TIVA with propofol-remifentanil.
Anesthesia methods and drugs affect postoperative nausea and vomiting. Propofol is known to have antiemetic effects. We compared the incidence of postoperative vomiting (POV) in children undergoing an adenotonsillectomy; anesthesia in one group was induced with propofol and maintained with sevoflurane and nitrous oxide, and the other group received total intravenous anesthesia (TIVA) with propofol-remifentanil. ⋯ If the development of POV in the early anesthetic recovery phase of children undergoing adenotonsillectomy is adequately prevented, propofol-induced anesthesia maintained with sevoflurane-nitrous oxide is as safe as TIVA with propofol-remifentanil.
