Thermoregulatory vasoconstriction and perianesthetic heat transfer.
Heat transfer between the core and its environment in normothermic and slightly hypothermic situations is determined largely by the influence of vasomotion on convection. Tonic vasoconstriction, the normal barrier to heat loss from the core, is impaired upon induction of anesthesia. The resulting dilation of the arteriovenous shunts leads to redistribution of heat from the core to the periphery, diminishing the temperature gradient between the two compartments. ⋯ Under normal conditions of mild thermal stress, thermoregulatory vasoconstriction is thus able to protect core temperature by reducing cutaneous heat transfer and functionally isolating the peripheral and core thermal compartments. Consequently, anesthetic-induced alterations in vasomotor tone is one of the major factors influencing core temperature in patients who are not actively cooled or warmed. In contrast, thermoregulatory tone is insufficient to prevent core temperature perturbations in patients undergoing vigorous cutaneous cooling or warming.

Comparative Study[Changes in intraocular pressure during anesthesia with intratracheal intubation or laryngeal mask].
To compare the effects of the laryngeal mask airway (LMA), and the tracheal tube (TT) insertion on intra-ocular pressure (IOP) in eye surgery. ⋯ LMA insertion does not elicit significant haemodynamic or IOP changes. Conversely, the TT increases HR, MAP and IOP. These changes can be deleterious in case of emergency surgery for perforating eye injuries. The LMA can be recommended as an alternative to TT in eye surgery, provided security rules are followed, because of the risk of displacement of LMA during surgery.

AIM. To evaluate the validity of general anesthesia using the laryngeal mask airway (LMA) in pediatrics in a series of 163 patients. MONITORING. ⋯ Measurement of every complication during and after anesthesia. CONCLUSIONS. In pediatric anesthesia LMA represents a good link between anesthetic equipment and the patient.

We did anesthetic management on a pediatric patient with Cornelia de Lange syndrome presenting a peculiar look, variable physical deformities, and some growth and mental retardations. An 8-year-old male patient was scheduled for inguinal hernioplasty under general anesthesia. ⋯ The area of skin incision was infiltrated with 0.25 % bupivacaine for the purpose of post-operative analgesia, and as a result, psychologically and physically stable condition was obtained during post-operative periods. It is necessary to understand not only the patient's physical conditions but also mental ones in order to make the anesthetic management safer and more satisfactory.
