Final answer:
The side-entry or lateral position during medical treatments can lead to complications such as atelectasis, decreased cardiac output, nerve injuries, skin breakdown, and venous pooling.
Step-by-step explanation:
The side-entry or lateral position in medical treatments refers to the patient lying on their side during a medical procedure. There are several potential disadvantages and complications to this method of treatment. Firstly, it can cause pressure on the dependent lung, potentially leading to atelectasis, which is the collapse or closure of a lung resulting in reduced or absent gas exchange. Another issue could be the decreased cardiac output due to the positioning, which may be detrimental to patients with cardiovascular issues. Additionally, there could be nerve injuries, specifically the peroneal nerve, due to pressure points related to how the patient is positioned on the operating table. Other possible complications include skin breakdown at pressure points and venous pooling in the dependent extremities.
