In the intensive care unit (ICU), analgesia and sedation are used to improve the comfort and safety of patients undergoing intensive care therapies. However, continuous administration of sedatives prolongs the time on mechanical ventilation and ICU stay. These adverse effects can be reduced by clear definition of the goals of sedation combined with a sedation protocol. ⋯ Adherence to the local sedation guideline was not high, and no significant change was seen after this simple intervention. Continuous education and discussion on the desirable and undesirable effects of sedation, followed by multidisciplinary re-evaluation of the current guideline, are due in our unit.

Case ReportsCapnography rapidly confirmed correct endotracheal tube placement during resuscitation of extremely low birthweight babies (< 1000 g).
During neonatal resuscitation, the routine use of capnography to verify correct placement of the endotracheal tube is not an established international practice. We present four cases that illustrate the successful use of immediate capnography to verify correct tracheal tube placement even in extremely low birthweight (ELBW) prematures (< 1000 g) during resuscitation. Based on this limited experience, we reached institutional consensus among paediatricians and anaesthesiologists that capnography should become standard monitoring during all endotracheal intubations in premature babies.

The effect of the lateral decubitus position on the intraocular pressure in anesthetized patients undergoing lung surgery.
Changing the body position alters the intraocular pressure (IOP). The aim of this study was to investigate the alteration in IOP of the eyes after a positional change from a supine position to a lateral decubitus position in anesthetized patients, in order to detect differences in IOP between the two eyes, possibly due to a gravity effect, in the lateral decubitus position. ⋯ The IOP was higher in the dependent eye than in the non-dependent eye in anesthetized patients in the lateral decubitus position, and the IOP in the dependent eye increased in anesthetized patients compared with that in awakened and supine-positioned patients.

The effects on the lower esophageal sphincter of sevoflurane induction and increased intra-abdominal pressure during laparoscopy.
Today sevoflurane is one of the most frequently used volatile anesthetics. The speed of induction can approach that of intravenous anesthetics, and case reports using sevoflurane induction for emergency anesthesia have been published. The purpose of this study in laparoscopic cholecystectomy patients was to investigate the effects of sevoflurane during inhalation induction on the lower esophageal sphincter pressure (LESP) and barrier pressure (BrP). The effects on lower esophageal sphincter (LES) and BrP of increased intra-abdominal pressure during laparoscopy were also evaluated. ⋯ BrP was kept positive in all patients after induction of anesthesia. Therefore, we believe that in combination with cricoid pressure, inhalation induction with sevoflurane might be a safe choice. As the adaptive increase in LESP during laparoscopy was not enough to retain a barrier pressure in all patients, it is important to be aware of the risk of regurgitation throughout the anesthesia.
