[Show abstract][Hide abstract] ABSTRACT: Computer-assisted three-dimensional reconstruction of the fetal human pancreas was prepared to reconsider topographical relation between the dorsal/ventral anlagen and the vascular supply.
Tissue sections from the upper abdominal viscera of three fetuses were examined. Sections were immunohistochemically stained to determine pancreatic polypeptide expression, a marker of the ventral pancreas.
The immunohistochemical findings were used to create three-dimensional computer-assisted reconstructions to identify pancreatic arteries. The narrowest part of the pancreas, or the neck, corresponding to a part of the dorsal pancreas, was located on the left side of the common bile duct, portal vein and gastroduodenal artery (GDA). The posterior arterial arcade accompanied the ventral pancreas, whereas the anterior arcade did not. In contrast to the GDA, the splenic artery was clearly separated from the neck in fetuses. The GDA appears to be the primary and stable arterial supply for the neck of the pancreas.
This observation may have implications for the preservation of the neck with the GDA during pancreaticoduodenectomy for benign and low-grade malignant diseases.

Even though perfusion is safer, incidents still occur. During the repair of a ventricular-septal defect in an 11-month-old infant, we experienced a critical incident related to the potential hazardous effect of volatile anesthetics on the polycarbonate connector of extra-corporeal circuit. The damage to the polycarbonate connector had occurred after spillage of isoflurane during the filling of the vaporizer, causing it to crack and leak. The incident was managed by replacement of the cracked connector during a temporary circulatory arrest. The patient was hypothermic and the time off bypass was less than 1.5 min. There were no neurologic sequelae, the patient made an uneventful recovery. In conclusion, the spillage of volatile anesthetics can cause cracks in the polycarbonate connector of the extra-corporeal circuit, leading to potentially interruption of CPB.

[Show abstract][Hide abstract] ABSTRACT: In the Korean National Health Insurance Corporation (KNHIC), payment for inhaled anesthetics are made according to the simulated dose and not the consumed dose. We compare the consumption of inhaled anesthetics according to fresh gas flow (FGF) and anesthetic circuits to compare the consumption of anesthetics and the guidelines for KNHIC payments.

[Show abstract][Hide abstract] ABSTRACT: A self-inflating bag resuscitator is universally used to ventilate patients during cardiopulmonary resuscitation and transfer. This device can be reused after sterilization and reassembly, and the mis-assembly of a resuscitator can possibly happen. We report here on a case of mis-assembly of a resuscitator valve that resulted to barotrauma and instability of a patient.

[Show abstract][Hide abstract] ABSTRACT: Nasal bleeding related to nasal trauma is the most common complication of nasotracheal intubation with a fiberoptic scope. When nasotracheal intubation with a fiberoptic scope is performed, profuse bleeding from the nasal cavity makes it difficult to handle a fiberoptic scope and may cause a hypoxemia. So when nasal bleeding occurs, it is important to suction the nasal cavity for easy handling of a fiberoptic scope. But, it may be difficult to suction in a nasal cavity with a fiberoptic suction port only. We report a patient with nasal bleeding following nasotracheal intubation with a fiberoptic scope because of articular trismus, and successful nasotracheal intubation utilizing a fiberoptic scope by suctioning with an extra suction apparatus.
