Chlorophyll a concentration of phytoplankton during a cruise of the 51st Japanese Antarctic Research Expedition in 2009-2010

Measurements of phytoplankton chlorophyll a concentration in seawater at depths less than 200 m were made in the Indian sector of the Southern Ocean during the 51st Japanese Antarctic Research Expedition (JARE) in the austral summer of 2009–2010. This expedition was the first cruise of the new icebreaker Shirase

Anestesia para cesariana em paciente com ausência unilateral isolada de artéria pulmonar

ResumoJustificativa e objetivosA ausência congênita unilateral de uma artéria pulmonar (ACAP) é uma anomalia rara. Embora existam vários relatos sobre pacientes grávidas com ACAP, não há relatos de casos que descrevam anestesia para cesariana em pacientes com ACAP.Relato de casoApresentamos uma paciente com ACAP que foi submetida a duas cesarianas, aos 24 e 26 anos, sob raquianestesia para a cirurgia e analgesia epidural para a dor no pós‐operatório. Nas duas cesarianas, a raquianestesia e a analgesia epidural possibilitaram o manejo bem‐sucedido da anestesia, sem a ocorrência de qualquer hipertensão pulmonar ou insuficiência cardíaca direita.ConclusãoRaquianestesia combinada com analgesia epidural é um método anestésico útil para cesarianas em pacientes com ACAP.AbstractBackground and objectivesCongenital unilateral absence of a pulmonary artery (UAPA) is a rare anomaly. Although there are several reports regarding pregnancy in patients with unilateral absence of a pulmonary artery, there are no case reports describing anesthesia for Cesarean section in a patient with unilateral absence of a pulmonary artery.Case reportWe present a patient with unilateral absence of a pulmonary artery who underwent Cesarean sections twice at the ages of 24 and 26 years under spinal anesthesia for surgery and epidural analgesia for postoperative pain relief. Both times, spinal anesthesia and epidural analgesia enabled successful anesthesia management without the development of either pulmonary hypertension or right heart failure.ConclusionSpinal anesthesia combined with epidural analgesia is a useful anesthetic method for a Cesarean section in patients with unilateral absence of a pulmonary artery
