Abdominal compartment syndrome can produce a critical situation if not diagnosed early and managed properly. We report a case of abdominal compartment syndrome that was caused by massive irrigation of surgical fluid during endoscopic lumbar diskectomy at the L4–L5 level. There was a sudden increase in peak inspiratory pressure during the operation, and the patient's tidal volume and blood pressure decreased. When the patient's position was changed from prone to supine, abdominal distension and cyanosis of both lower extremities were discovered. Ultrasonic findings showed fluid collection in both the chest and intra-abdominal cavity. Thoracentesis and abdominal decompression surgery were performed, and the patient's overall state improved. We concluded that irrigation fluid used during the endoscopic operation leaked into the retroperitoneal space and caused abdominal compartment syndrome.

Development of transfusion-related acute lung injury (TRALI), a non-cardiogenic pulmonary edema, after blood transfusion, is a rare but potentially leading cause of mortality from blood transfusion. We report on a case of TRALI in a 51-year male with acute calculous cholecystitis and liver cirrhosis. As preoperative treatment, he was given ten units of fresh frozen plasma (FFP) for 3 days before the operation. During the transfusion of the 10th unit of FFP, he experienced a sudden onset of hemoptysis, tachypnea, tachycardia, and cyanosis. Bilateral pulmonary infiltration not observed on the chest X-ray at the visit was newly developed. There was no evidence of volume overload but severe hypoxemia. Blood transfusion was stopped and he recovered fully after 8 days of oxygen therapy through a nasal cannula. Although HLA and HNA antibodies were not detected in the donor's blood, HLA antibodies (A2, B57, B58) were detected in the patient's blood. We reported this meaningful case of TRALI that occurred after transfusion of only fresh frozen plasma which did not contain human leukocyte antibody in a patient with HLA antibody.

Extra-adrenal pheochromocytoma is rare and presents variable symptoms. Its difficulty to diagnosis delays appropriate treatment. We would like to report an unusual case of extra-adrenal pheochromocytoma. The patient came to the emergency room with dyspnea, palpitation, and cyanosis. He had a history of hospitalization for Fontan operation due to congenital heart disease. Despite medication, his blood pressure remained high. After additional laboratory and image exams, he was diagnosed with extra-adrenal pheochromocytoma and had surgical treatment. The final pathology report was extra-adrenal pheochromocytoma with high risk of malignancy. The postoperative course was uneventful and showed normal laboratory results even after 3 months of outpatient follow-up. Extra-adrenal pheochromocytoma presents variable symptoms. We should consider endocrinologic diseases like extra-adrenal pheochromocytoma in cases presenting with palpitation and high blood pressure, even with a past history of cardiac surgery.

Transfusion related acute lung injury (TRALI) is rare, but can sometimes lead to serious complication, and increases transfusion related mortality. We report on a case of a 21-year-old female with a femoral arterial rupture. Because of a massive hemorrhage, she was given nine units of packed red blood cell (RBC), nine units of fresh frozen plasma (FFP), and eight units of platelet. One hour after the end of blood transfusion, the patient experienced a sudden onset of dyspnea, tachypnea, cyanosis, and hypoxemia in the recovery room. Her breathing sounds were markedly decreased and bilateral diffuse crackles were detected. There were no signs of volume overload. A chest X-ray showed bilateral coarse alveolar infiltrates and a CT scan showed bilateral non-cardiogenic diffuse pulmonary edema with pleural effusion. Pressure support ventilation (PSV) and noninvasive positive pressure ventilation (NIPPV) were applied via a full-face CPAP mask after changing to prone position. She showed slow improvement, and achieved a full recovery over the next seven days.

OBJECTIVEA prospective study was conducted to probe into the relationship between arterial oxygen partial pressure (PaO2) and brain injury during cardiopulmonary bypass (CPB) in infants with cyanotic congenital heart disease (CHD).

METHODEnrolled in the study were 45 cyanotic infants, who were less than three years old and underwent corrective cardiac surgery from August 1(st), 2010 to January 31(st), 2011 at Guangdong General Hospital. All the infants had a pulse oxygen saturation (SpO2) lower than 85% and were randomly allocated into three groups by a specific computer program. In controlled group 1 (G1 group), PaO2 levels were controlled at 80 - 120 mm Hg (1 mm Hg = 0.133 kPa) during CPB; in controlled group 2 (G2 group), PaO2 levels at 120 - 200 mm Hg during CPB; while in uncontrolled group (G3 group), PaO2 levels were at 200 - 400 mm Hg during CPB. Blood samples were collected just before starting CPB, at the end of CPB, and at 3 h, 5 h, and 24 h after CPB (T1, T2, T3, T4, T5) for the determination of serum concentrations of protein S100β, neuron specific enolase (NSE), and adrenomedullin (ADM) by ELISA.

RESULTProtein S100β rose significantly after starting CPB. In group G3, it reached a peak of (699 ± 139) ng/L by the end of CPB, significantly higher than those in groups G1 and G2 [(528 ± 163) ng/L and (585 ± 155) ng/L], and was positively correlated with PaO2 levels (r = 0.526, P < 0.01). NSE levels of group G1 were continuously rising after starting CPB and reached significantly high levels at 3 h or 5 h after CPB [(12.2 ± 3.4) µg/L and (12.3 ± 3.7) µg/L], while those of group G2 rose significantly during CPB [(10.9 ± 4.8) µg/L] and even higher at 3 h or 5 h after CPB [(12.6 ± 5.1) µg/L and (13.2 ± 5.4) µg/L]. NSE levels of group G3 rose significantly during CPB and maintained at a high level [(12.2 ± 5.7) µg/L] afterwards. There was no significant difference in serum ADM concentrations among different time points in each group and among these three groups. All the infants were discharged from the hospital without any obvious nervous symptom and sign.

CONCLUSIONHigh PaO2 during CPB in infants with CHD might cause an increase of serum protein S100β and NSE, indicating that brain injury might become worse with a higher PaO2 and might be positively correlated with PaO2 during CPB.

BACKGROUNDCyanotic patients have potential growth retardation and malnutrition due to hypoxemia and other reasons. Ghrelin is a novel endogenous growth hormone secretagogue that has effects on growth and cardiovascular activities. The aim of this study was to evaluate the plasma level and myocardial expression of ghrelin and insulin-like growth factor-1 (IGF-1) using an immature piglet model of chronic cyanotic congenital heart defects with decreased pulmonary blood flow.

METHODSTwelve weanling Chinese piglets underwent procedures of main pulmonary artery-left atrium shunt with pulmonary artery banding or sham operation as control. Four weeks later, hemodynamic parameters were measured. Enzyme-linked immunosorbent assay for plasma ghrelin and IGF-1 level measurement were performed. Ventricular ghrelin and IGF-1 mRNA expressions were measured by quantitative real-time polymerase chain reaction.

RESULTSFour weeks after surgical procedure, the cyanotic model produced lower arterial oxygen tension ((68.73 ± 15.09) mmHg), arterial oxygen saturation ((82.35 ± 8.63)%), and higher arterial carbon dioxide tension ((51.83 ± 6.12) mmHg), hematocrit ((42.67 ± 3.83)%) and hemoglobin concentration ((138.17 ± 16.73) g/L) than the control piglets ((194.08 ± 98.79) mmHg, (96.43 ± 7.91)%, (36.9 ± 4.73) mmHg, (31.17 ± 3.71)%, (109.83 ± 13.75) g/L) (all P < 0.05). Plasma ghrelin level was significantly higher in the cyanotic model group in comparison to the control (P = 0.004), and the plasma IGF-1 level was significantly lower than control (P = 0.030). Compared with control animals, the expression of ghrelin mRNAs in the ventricular myocardium was significantly decreased in the cyanotic model group (P = 0.000), and the expression of IGF-1 mRNAs was elevated (P = 0.001).

CONCLUSIONSChronic cyanotic congenital heart defects model was successfully established. Plasma ghrelin level and myocardial IGF-1 mRNA expression were significantly up-regulated, while plasma IGF-1 level and myocardial ghrelin mRNA expression were down-regulated in the chronic cyanotic immature piglets. The ghrelin system may be an important part of the network regulating cardiac performance.

Methemoglobinemia is an uncommon but potentially fatal disorder. Most cases have no adverse clinical consequence and require no treatment, but methemoglobinemia is often overlooked as a cause of low oxygen saturation, and often mistaken for the more common causes of hypoxia by anesthesiologists despite simple bedside tests that indicate the presence of this treatable abnormality. We present a 68-year-old female patient who underwent gastrectomy for advanced gastric cancer with bleeding. In the preoperative period, the patient showed cyanosis and oxygen saturation was 85% by pulse oximeter, but oxygen saturation by arterial blood gas analysis was 100%. After tracheal intubation, the methemoglobin level was 18.3%. Ascorbic acid and methylene blue were administered. During preanesthetic evaluation, the patient had not informed the anesthesiologist that she had been taking dapsone.

Microscopic examination of peripheral blood smear (PBS) for detection of microorganisms is simple method that can be used for doctors to confirm the septicemia more swiftly and to select more specific therapy. But it is unusual to find microorganisms in PBS. We report a case of gram negative bacteremia diagnosed by PBS in a severe thrombocytopenic pediatric surgical patient. A 6-month and 2 week old baby with cyanosis was diagnosed congenital heart diseases such as transposition of great arteries, atrial septal defect, and patent ductus arteriosus. The infant underwent surgical operations and the postoperative platelet count progressively decreased in spite of transfusion of multiple platelet concentrates. We performed routine examination of a PBS for evaluation of severe thrombocytopenia. The PBS revealed severe thrombocytopenia, leukopenia with left shifted and some extracellular bacilli. Toxic granulations, toxic vacuoles and some bacilli were observed in the neutrophils. The bacilli were identified as Pseudomonas aeruginosa and Serratia marcescens in blood culture. To our knowledge, this is the second case of bacteremia diagnosed by PBS before the positive blood culture in Korea. We suggest that a PBS is useful for the rapid detection of organisms in cases of septicemia with severe thrombocytopenic pediatric surgical patient.

PURPOSE: This study was conducted to investigate the characteristics of drug induced anaphylaxis and anaphylactic shock in patients who were admitted to the emergency department. METHODS: We retrospectively collected the data on patients with drug induced anaphylaxis and who were admitted to the emergency department from January 2001 to June 2009. The study group was divided into the non-shock and shock groups according to whether the systolic blood pressure more than 90 mmHg. The initial demographic data, the causes of drug-induced anaphylaxis, the clinical manifestations, the treatment and the prognosis were reviewed for 72 patients. RESULTS: The mean age of the study subjects was 47.9+/-14.2 years old and there were 40 male patients and 32 female patients. There were 26 patients in the non-shock group and 46 in the shock group. The mean age was older in the shock group than in the non-shock group (51.5+/-15.1 vs 42.5+/-10.6, p-0.002). A history of drug allergy was more common in the shock group, but no difference was found for the comorbid chronic diseases between the two groups. Radio-contrast media was the most common cause, followed non-steroidal anti inflammatory drugs and antibiotics, but there is no difference in the causes between the two groups. The symptoms of cyanosis, syncope, sweating and dizziness were more frequently manifested in the shock group. The administration of intravenous fluid and injection of subcutaneous epinephrine at the emergency department were more frequent in the shock group than in the non-shock group. CONCLUSION: For the patients who were admitted to the emergency department with drug induced anaphylaxis, the mean age was older and the symptoms of cyanosis, syncope, sweating, dizziness were more frequent in the anaphylactic shock patients than in the non-shock group. More treatments were given at the emergency department to the anaphylactic shock patients.
