Brief Summary

The objective of this clinical trial is to determine the effectiveness of pain reduction between an experimental treatment and the usual one when removing thoracic drains in post cardiac surgery patients, in a Cardiovascular Critical Patient Unit, in Temuco, between the years 2024- 2026. Its safety will also be analyzed. The main questions to be answered are:

• What is the effectiveness of non-pharmacological therapies in reducing pain in the removal of chest drains in post-operated patient of cardiac surgery, in Cardiovascular Critical Patient Unit, Temuco, between the years 2024- 2026?

Participants:

• Two non-pharmacological therapies will be applied, to one group aromatherapy with lavender essential oils, which were previously submitted to oil property analysis. And another group with local cold therapy, there will also be a control group with the usual pharmacological therapy.
• All the groups will receive the usual pharmacological treatment, the non pharmacological therapies will only be of support, in no case they will replace the usual medical therapy.

Detailed Description

Controlled clinical trial, randomized, single-blind, with a sample of 100 postoperative cardiac surgery patients who meet inclusion and exclusion criteria. The sample will be obtained by two nurses with more than 8 years of experience in cardiac intensive care and specializations, of these patients all will receive the usual pharmacological therapy, will be divided into three groups: 25 patients (local cold); 25 patients (aromatherapy); 50 patients (with usual pharmacological therapy, indicated by medical team, without adding TNF). Data will be collected through a form. The database will be exported to STATA CORP18 software, where they will be analyzed. The ethical requirements of Ezequiel Emanuel will be considered.

Study Groups

Local cold application group

patients with indication for removal of drains after cardiac surgery, with analgesia according to the protocol indicated by the resident physician, to whom local cold will be applied . If after the removal of drains there is pain that does not subside with complementary therapy, extra analgesia may be requested.

Group Type: EXPERIMENTAL

Local cold therapy.

Intervention Type: OTHER

It will be applied by means of a refrigerated unit based on gel pack, these units will be stored in the refrigerator of the Unit, which is kept between 2 - 6 degrees, the application protocol is described in Annex B, this was reviewed in conjunction with quality nurses of the Cardiovascular Unit, to avoid biases.

Aromatherapy group

Patients with indication for removal of drains after cardiac surgery, with analgesia according to protocol indicated by resident physician, who at the time of removal of drains will be applied aromatherapy with lavender oil.

Control group.

Patients with indication for removal of drains after cardiac surgery, with analgesia according to the protocol indicated by the resident physician, the routine technique will be performed.
