    (1998) Toro, J; Vega, JD; Khan, AS; Mills, JN; Padula, P; Terry, W; Yadón, Z; Valderrama, R; Ellis, BA; Pavletic, C; Cerda, R; Zaki, S; Wun-Ju, S; Meyer, R; Tapia, M; Mansilla, C; Baro, M; Vergara, JA; Concha, M; Calderon, G; Enria, D; Peters, CJ; Ksiazek, TG
    An outbreak of 25 cases of Andes virus-associated hantavirus pulmonary syndrome (HPS) was recognized in southern Chile from July 1997 through January 1998. In addition to the HPS patients, three persons with mild hantaviral disease and one person with asymptomatic acute infection were identified. Epidemiologic studies suggested person-to-person transmission in two of three family clusters. Ecologic studies showed very high densities of several species of sigmodontine rodents in the area.

    Analgesia after thoracotomy: Epidural fentanyl/bupivacaine compared with intercostal nerve block plus intravenous morphine
    (W B SAUNDERS CO-ELSEVIER INC, 2004) Concha, M; Dagnino, J; Cariaga, M; Aguilera, J; Aparicio, R; Guerrero, M
    Objectives: Intercostal nerve blockade plus intravenous (IV) patient-controlled analgesia (PCA) could be an easier and safer alternative to epidural analgesia for postthoracotomy pain, but information about the efficacy of this technique is scarce. The objective of this randomized study was to compare the quality of analgesia and lung function in 2 groups of patients undergoing pulmonary surgery through a posterolateral thoracotomy.

    Intramucosal gastric pH during liver transplantation
    (BLACKWELL SCIENCE LTD, 2000) Concha, M; Dagnino, J; Altermatt Couratier, Fernando René
    Intramucosal gastric pH (pHi) was measured during liver transplantation in a 3-year-old girl. The basal value was below that reported as normal for paediatric patients under stable normal ventilatory and haemodynamic conditions. Additional reductions of the pHi were observed during the hepatectomy and anhepatic phase, in the absence of haemodynamic or ventilatory alterations. The reperfusion phase was characterized by a progressive return toward normal values. Because we did not measure oxygen delivery and consumption, we cannot determine whether the reduction of the pHi was due to insufficient oxygen delivery or a result of the vascular anatomical alterations due to the surgical procedure.
