Pulse rhythm01:30

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...
Blinding01:11

Blinding

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
Holter Monitor: 24-Hour Monitoring01:23

Holter Monitor: 24-Hour Monitoring

Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

Area of Science:

  • Pain Management
  • Non-invasive Therapies
  • Postoperative Care

Background:

  • Pulsed shortwave therapy (PSWT) is a non-pharmacologic and non-invasive treatment option.
  • It may offer analgesic benefits without significant side effects.
  • This study aimed to evaluate the feasibility and preliminary treatment effects of PSWT.

Purpose of the Study:

  • To assess the feasibility of a PSWT protocol in patients undergoing surgery.
  • To estimate the treatment effects of PSWT on postoperative pain.
  • To provide data for planning future definitive trials.

Main Methods:

  • A pilot randomized controlled trial was conducted.
  • Participants undergoing cholecystectomy or hip/knee arthroplasty received either active PSWT or a sham treatment for eight days.
  • Pain intensity was measured using a numeric rating scale over the first seven postoperative days.

Main Results:

  • No significant complications were reported with PSWT.
  • The active PSWT group showed a statistically significant reduction in summed daily pain intensity scores compared to the sham group (p=0.032).
  • No significant difference in oxycodone consumption was observed between groups (p=0.761).

Conclusions:

  • PSWT is a feasible treatment for both inpatient and outpatient postoperative pain management.
  • The therapy demonstrated a reduction in pain during the first postoperative week.
  • Further research is needed to confirm these preliminary findings and explore its efficacy compared to standard analgesics.
