Primum non nocere

Hipócrates, ao redor do ano 430 aC, propôs aos médicos, no parágrafo 12 do primeiro livro da sua obra Epidemia:
"Pratique duas coisas ao lidar com as doenças; auxilie ou não prejudique o paciente" - ou seja, primum non nocere - primeiro de tudo, não provoque nenhum dano.

Hemorragia por varizes esofágicas: meta-análise dos tratamentos

Ligamento da banda varicosa versus beta-bloqueadores para prevenção primária de hemorragia por varizes esofágicas: uma meta-análise

O ligamento das varizes esofágicas (LVE) pode reduzir a taxa de primeira hemorragia em 45-52% comparado com beta-bloqueadores (BBs). Meta-análise de novos estudos comparativos mostraram que o risco relativo para primeiro sangramento por varizes esofágicas favorece o LVE, com um número necessário para tratar de 13, entretanto não foram observadas diferenças entre mortalidade relacionada com os sangramentos ou mortalidade de qualquer causa.

Os autores concluíram que o ligamento das varizes esofágicas é superior na prevenção do primeiro sangramento, com poucos efeitos colaterais resultando na descontinuação do tratamento.

Já temos aproximadamente 50 cabeças pensantes, um verdadeiro caldeirão cultural. Gostaria que fizesse parte da minha seção com uma subseção dentro a sua área de atuação.
Caso se interesse, aguardo manifestação da sua parte para te dar mais detalhes.
Obrigada.
