Abstract

Objectives: We compared effects of mechanical and manual ventilation during transport to the intensive care unit(ICU) in cardiac surgeries. Materials and methods: After ethical approval, 66 patients (ASAgrade II and III, 20-80years) were assigned randomly. Ventilation during transport to ICU was performed manual (Group EV; n=36) or mechanical ventilation (Group MV; n=30). Measurements were recorded: operation room (A), during transport (T) and in ICU (YB). Systolic, diastolic pressures (SAP, DAP), pulmonary arterial pressure (PAP), pulmonary capillary wedge pressure (PCWP), central venous pressure (CVP), heart rate (HR), cardiac output (CO), blood gases (pH, PCO2, PO2, BE) and peripheral oxygen saturation (SpO2) were recorded. Stroke volume index (SVI), systemic and pulmonary vascular resistance indices (SVRI, PVRI) and mean arterial pressures(MAP) were calculated. Results: Patients were similar. Duration of transport was shorter in Group MV (p< 0.01). The alterations in HR, MAP, DAP, CVP, PAP, PCWP, PVRI, SVRI, SVI, CO, SpO2 were similar, the increase in SAP during T period was higher in Group MV (p

Kardiyak cerrahi ameliyatlarından sonra hastaların yoğun bakıma transportları sırasında mekanik ventilasyon ile elle ventilasyonun karşılaştırılması

Abstract

Amaç: Kardiyak ameliyatlar sonrası, yoğun bakıma transportta mekanik ve el ventilatörünün etkilerini karşılaştırdık. Gereç ve yöntem: Elektif kardiyak cerrahi uygulanan 66 hasta (ASA II- III, 20-80yaş) rastgele iki gruba ayrıldı. Hastaların yoğun bakıma transportlarında el ventilatörü (Grup EV; n=36) veya mekanik ventilatör (Grup MV; n=30) kullanıldı. Ölçümler, ameliyathane masasında (A), transport esnasında (T) ve yoğun bakımda (YB) kaydedildi. A ve YB\'da sistolik arter basıncı (SAB), diyastolik arter basıncı (DAB), kalp atım hızı (KAH), santral venöz basınç (SVB), ortalama pulmoner arter basıncı (PAB) ve pulmoner arter kapiller oklüzyon basıncı (PAOB), kalp debisi (KD), kan gazları ve periferik oksijen saturasyonu (SpO2) değerleri, T\'ta SAB, DAB, KAH, SpO2 ve transport süresi (TS) kaydedildi. Atım hacmi indeksi (Stroke volume index;SVI), sistemik vaskuler rezistans indeksi (SVRI), pulmoner vasküler rezistans indeksi (PVRI), ve ortalama arteriyel basınç (OAB) hesaplandı. Bulgular: Hasta özellikleri benzerdi. Transport süresi MV Grubunda daha kısaydı (p< 0.01). Gruplarda KAH, OAB, DAB, CVP, PAP, PCWP, PVRI, SVRI, SVI, CO, SpO2\'deki değişiklikler farksızken, T döneminde SAB\'da Grup MV\'deki artış belirgindi (p
