An interventional study of Placebo and TENS low frequence group in Cardiac Surgery and Transcutaneous Electric Nerve Stimulation, sponsored by Universidade Federal de Pernambuco. Completed at 1 site in Brazil. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-03-25.
Sponsored by Universidade Federal de Pernambuco · Not applicable, Interventional, and Treatment
Cardiac Surgery (CH) aims to increase survival and improve quality of life in eligible cardiac patients. However, as with any invasive intervention, pain is one of the main complaints of patients in the post-surgical period. This research is justified by the evaluation of the potential impact of the use of TENS as an alternative for analgesia in reducing the length of hospital stay and directly in the effective cost of patients undergoing cardiac surgeries, in reducing morbidity and mortality, as well as in the quality of life and early return to their daily activities, in addition to reducing the use of drugs and potentially their side effects. The objective of this study is to evaluate the effect of TENS for analgesia in hospitalized patients undergoing cardiac surgery, investigating its efficacy, safety and impact on postoperative recovery.
Universidade Federal de Pernambuco is the lead sponsor of 161 studies on the registry; 21 are open to participants now.

Exclusion Criteria:
This group will not actually receive a treatment current, being subjected only to the device connected without current.
Device: Placebo
In this group, patients will undergo the hospital's usual analgesia and physiotherapy routine, plus TENS with a frequency of 140 Hz and a pulse width of 50 µs.
Device: Conventional TENS
Patients in this group will undergo the hospital's usual analgesia and physiotherapy routine, plus conventional TENS with a low frequency of 5 Hz and a pulse width of 250 µs
Device: TENS low frequence group
these patients will be subjected to the same usual routine of pharmacological analgesia, consisting of the administration of 1g of dipyrone at the discretion, with escalation to tramal (dose) and physiotherapy in the hospital ICU, in addition to an application of TENS, with the device turned on, with programming on channels that are not connected to the patients, so as to generate visual and auditory feedback.
Patients in this group will undergo the hospital usual analgesia and physiotherapy routine, in addition to conventional TENS with a low frequency of 5 Hz and a pulse width of 250 µs.
In this group, patients will undergo the usual routine of analgesia and hospital physiotherapy, in addition to TENS with a frequency of 140 Hz, pulse width of 50 µs.
