Unusual Capnography due to Incorrect Assembly of Spring with Absorber Valve into Breathing Circuit - Experience of Normocarbia: A Case Report: Byong Soo Jang, Chang Gyu Han, Dong Gun Lim; Korean J Crit Care Med. 2006;21(1):63-68.

Abstract PDF: A focus on patient safety has heightened the awareness of pateint mornitoring. The importantce of clinical application of capnography continues to grow, as reflected by the increasing number of medical societies recommending its use. We recently encountered an abnormal capnography undergoing gastrectomy. It was noted that the waveform was not sustained zero-baseline formation as seen during inspiratory phase, immediately upsloping for expiratory plateau followed by inspiratoy downsloping as like a shape of curare cleft. But PaCO2 was within normal range. We found that the source of the problem was the incorrect (bottom up) assembly of spring with absorber valve into the CUBE, the circle breathing system of Dameca Ventilator. Spring with absorber valve divides CUBE circle into inspiratory and expiratory space. We concluded that the unusual capnography was resulted from the incorrect assembly of it, subsequently mixing of inspiratory and exhaled gases and rebreathing was occurred with the block of a gas flow to CO2 canister. After correcting assembly, the capnography was normalized.

Labor Analgesia with Epidural Blockade in Parturient with Peripartum Cardiomyopathy: A Case Report: Tae Ha Ryu, Jae Hoon Jeong, Dong Gun Lim, Si Oh Kim; Korean J Crit Care Med. 2004;19(2):143-147.

Abstract PDF: Peripartum cardiomyopathy (PPCM) is an unusual and uncommon causes of antepartum and postpartum heart failure, which may result in severe cardiac failure and death. PPCM is often unrecognized as symptoms of normal pregnancy commonly mimic those of mild heart failure but can rapidly progress to cardiac failure. We presented a case of elective labor induction in a patient with peripartum cardiomyopathy. A epidural analgesia technique was performed without difficulty for labor analgesia in parturient with peripartum cardiomyopathy. Her post-delivery course was uncomplicated but her baby has died due to respiratory failure. We suggest that vaginal delivery with careful incremental epidural alnalgesia in patient with PPCM is acceptable methods and close peripartum monitoring is essential in the management of PPCM.

Hemodynamic Changes during Isolated Liver Hemoperfusion of Hepatoma: Seong Jo Ha, Yoon Jin Hwang, Dong Gun Lim; Korean J Crit Care Med. 2004;19(2):115-120.

Abstract PDF: BACKGROUND
To analyze hemodynamic changes during single catheter technique of hepatic venous isolation and extracorporeal charcoal hemoperfusion for malignant liver tumor. METHODS: Drugs for chemotherapy were infused to the liver through hepatic artery. With 4-lumen- 2-balloon (4L-2B) catheter, hepatic venous blood was circulated to the extracorporeal charcoal system. During extracorporeal charcoal system circulation, drugs were eliminated and the blood was reinfused to supra-hepatic vein-IVC. At the same time, IVC was clamped. Systemic vascular resistance index (SVRI), cardiac index (CI), stroke volume index (SVI), mean arterial pressure (MAP), heart rate (HR) and arterial blood gas were measured after 4L-2B catheter insertion (T1), during test circulation (T2), after 20min chemotherapy (T3) and after 10min reperfusion (T4). RESULTS: MAP was decreased at T3 compared to T1 and increased at T4 compared to T3. CI was decreased at T3 and increased at T4 compared to T1. SVRI was decreased at T4 compared to T1. HR was increased at T2 and T3 compared to T1. SVI was decreased at T2 and T3 compared to T1. CONCLUSIONS: During clamping of IVC, MAP is decreased by decreased SVI in spite of increased HR. After IVC is released and the stagnated blood of lower extremity is recirculated, the MAP is returned to the value of after catheter insertion by increased SVI in spite of decreased SVRI.
