Resumo
Objetivo: Comparar os efeitos hemodinâmicos de dois modos diferentes de ventilação (volume controlado e volume controlado por pressão garantido) em pacientes submetidas a cirurgias ginecológicas laparoscópicas com posição de Trendelenburg exagerada.
Métodos: Trinta pacientes submetidos a operações de ginecologia laparoscópica foram ventilados usando o modo de volume controlado por volume (Grupo CV) ou o modo de volume garantido por pressão controlada (Grupo VGPC) (n = 15 para ambos os grupos). As variáveis hemodinâmicas foram medidas usando o Método Analítico de Registro de Pressão por canulação da artéria radial, além das pressões máximas e médias das vias aéreas e volume corrente expirado.
Resultados: O único achado notável foi um índice cardíaco mais estável no Grupo VGPC, onde outros parâmetros hemodinâmicos foram semelhantes. O volume corrente expirado aumentou no Grupo CV, enquanto o pico de pressão nas vias aéreas foi menor no Grupo VGPC.
Conclusão: o VGPC causa menos perturbações hemodinâmicas medidas pelo Método Analítico de Registro de Pressão (MARP) e permite melhor controle hemodinâmico intraoperatório na posição de Trendelenburg exagerada em cirurgia laparoscópica.
