Pacemaker and implantable cardioverter defibrillator codes were made to to protect the pacemaker-dependent patient during diathermy, electrocautery or other therapy using monopolar and bipolar snare with a high-frequency current

Diathermy can interfere with both EEG and ECG monitoring electrodes. Of greater consequence is the interaction between EMI and cardiac pacemakers or implantable defibrillators. Bipolar is safer than monopolar, but can still cause interference. The effects are unpredictable and include inappropriate pacing, damage to the device, inappropriate

Diathermy is one of medical nearly used in all surgeries. I hope you like this vid Diathermy and Pacemakers • Pacemakers may get inhibited during diathermy use • may revert to fixed rate of pacing • Magnet used to reset it • Alternative modes like ultrasonic scalpel should be used 27. Monopolar diathermy: - Current exits at a point distant from surgery site ∴ need to ensure that current density is low enough, so no injury at this point - Neutral plate has large SA & applied over an area of good supply Improperly applied plate: i) reduced area ii) increased impedance - possibly more heat generation & burns Background: This study aimed to quantify the clinical parameters of mono- and bipolar instruments that inhibit pacemaker function. The specific aims were to quantify pacer inhibition resulting from the monopolar instrument by altering the generator power setting, the generator mode, the distance between the active electrode and the pacemaker, and the location of the dispersive electrode. Diathermy In Surgery is usually better known as “electrosurgery“. (It is also referred to occasionally as “electrosurgical diathermy“).

Monopolar diathermy pacemaker

Bipolar is preferred over unipolar diathermy. Used in short bursts rather than prolonged use. Bipolar diathermy should be applied well away from the pacemaker and its wiring. Channeling effects if used on viscus with narrow pedicle (e.g. penis or testis) Surgical diathermy or electrosurgery may be monoterminal, monopolar or bipolar: Monoterminal electrosurgery.

In cardiology, monopolar diathermy is extensively deployed in patients to support permanent pacemaker (PPM) implantation and extraction. While diathermy helps with adequate hemostasis and reduces bleeding complications, it may rarely be associated with fatal dysrhythmias.

directions of “Monopolar dispersed current” when used near/over a DBS system. therapeutic ultrasound diathermy) is contraindicated because diathermy's energy by or adversely affect medical equipment such as cardiac pacemakers MONOPOLAR.

For pacemakers, brief consideration should be given to the patient’s reliance on the implanted device. Among patients with cardiac pacemakers, approximately 20% are dependent on their pacemaker for moment-to-moment maintenance of adequate rhythm and hemodynamics. This group of patients has a greater risk in the event of de-

The electromagnetic waves used in diathermy may interfere with either device’s pulse generator. Pacing inhibition and triggering, mode switching, incorrect detection of tachyarrhythmia, device reset, myocardial burns, VF and death have been reported in patients undergoing surgical procedures with diathermy.18, –, 20 In patients who are ‘pacemaker dependent’ with sensing pacemakers, endoscopists should be aware of the theoretical risk that delivery of diathermy could be interpreted If detectable pacemaker inhibition occurs with diathermy the surgeon should be informed immediately and the steps described above taken to reduce the effects. If monopolar diathermy has to be used extensively to control the bleeding and pacing is significantly affected then an external magnet may be tried as a last resort. Comparison of lateral thermal spread using monopolar and bipolar diathermy, the Harmonic Scalpel and the Ligasure.
Fixed vs growth mindset

This can lead to failure of the device, however this risk is reduced with the use of bipolar (instead of monopolar).

Bipolar diathermy does not usually affect pacing if site is distant from leads/box •Patient shivering, positioning may result in lead displacement and pacemaker failure If detectable pacemaker inhibition occurs with diathermy the surgeon should be informed immediately and the steps described above taken to reduce the effects.

They can often put the pacer into a mode where it is less susceptible to interference and reprogram it if it goes into reset mode. 2015-07-06 · Monopolar electrosurgery passes current through most of the patient’s body, to the plate located elsewhere. Because the current density rapidly decreases, it only creates an incision or coagulates at the surgical site. Bipolar electrosurgery is considered safer for patients with pacemakers in situ. Electrosection uses an monopolar electrode to produce low-voltage and high-amperage current at higher power than is used for electrocoagulation. The current is highly focused to vaporise tissue with minimal peripheral heat damage.

Pacemakers Unipolar diathermy can inhibit or permanently damage pace-makers. If diathermy is essential, the bipolar variety should be used. However, bipolar diathermy should be applied well away from the pacemaker and its wiring. Key references Bedford G, Bell K. Notes for a tutorial in the operating theatre.CPD Anaesth 2000;2:97–100

It can inhibit pacing, damage pulse generator, and cause inappropriate tachycardia therapy. Bipolar diathermy should be used in preference to monopolar diathermy to reduce the risk of EMI. The degree of dependency on the implanted device and the potential consequences of pacing inhibition should be established.
