This brief report summarizes three cases of patients who suffered full-thickness burns following electrosurgery due to faulty application of the grounding pad. The grounding pad, which is meant to provide a safe exit for electric current, failed to make adequate contact with the skin in all three cases. This resulted in heat generation and burns at the contact site. The report aims to increase awareness among surgical staff of this avoidable hazard and promote safety protocols like ensuring proper grounding pad placement and use of bipolar cautery to eliminate grounding pad burns.

What is MIS?
A minimally invasive medical procedure is defined as one that is carried out by entering the body through the skin or through a body cavity or anatomical opening, but with the smallest damage possible to these struct uresIncludes laparoscopic, endoscopic, and other approaches.
Why MIS?
Decreased patient pain
Decreased patient recovery period
Possible decrease in inflammatory response in the patient which may prove to have a better outcome in oncologic operations.
Distant future
In the distant future, there will be a para- digm shift with the development of non-inva- sive surgical techniques in combination with nanotechnologies and a new era in the devel- opment of surgery, and subsequently in surgi- cal techniques, will be opened.
Nanotechnology is an umbrella term for materials and devices that operate at the nanoskill (1 billionth of a meter). In terms of scale, a nanometer is approximately one 1/8000 of a human hair or 10 times the diam- eter of a hydrogen atom. The size of the device can vary but starts from a ten thou- sand-logic element system that will occupy a cube of no more than one hundred nanome- ters. This is a volume slightly larger than 0.001 cubic microns. This would be sufficient to hold a small computer. For example, if red blood cells are approximately eight microns in diameter, the 100 nanomicroprocessor will be 80 times smaller than a red blood cell. Devices this size could easily fit into the circulatory system and could even conceivably enter indi- vidual cells.
Operating theater books contain detailed records of surgical procedures and patients, which are used for planning and ordering supplies. These confidential records provide information on patient care journeys. Traditional paper-based operating theater books included patient names, ages, addresses, diagnoses, attending medical staff, dates and times of operations, and anesthetics used. While some organizations still use handwritten records, computer-based systems provide more secure, efficient access to records for medical staff in emergencies. Computer networks allow records to be easily accessed from any location in the hospital and save medical personnel time retrieving files. Computerized records also improve patient care, safety, and decision making.

Surgical site infections are infections that occur after surgery in the part of the body where surgery took place. They can range from minor superficial infections to more serious deep tissue infections. Surgical site infections account for around 20% of all healthcare-associated infections and at least 5% of patients who undergo surgery will develop a surgical site infection. The risk factors include patient characteristics like age, diabetes, and obesity as well as surgical factors like long duration of surgery, improper skin preparation, and poor aseptic technique. Preventing surgical site infections requires strategies like proper patient skin preparation before surgery, appropriate use of antimicrobial prophylaxis during surgery, and careful wound care after surgery.
An exploratory laparotomy is a surgical procedure where the abdomen is opened to examine the internal organs. It is performed under general anesthesia through an upper midline incision. Indications include trauma, infections, malignancy, complications of other procedures, and removal of foreign bodies. During the procedure, the surgeon examines the abdominal organs and treats any issues found. Potential complications include ileus, infection, hernia, and adhesive obstruction.

Hastened Attachment Of A Superficial Inf Epigastric Flapguest1c9ac82
This case report describes using the vacuum-assisted closure (VAC) device to hasten the attachment of a superficial inferior-epigastric artery flap used to reconstruct a third-degree burn injury on the hand of a 33-year-old patient. The VAC system was applied in a glove-like shape beneath the flap. After 4 days, hastened attachment of the flap to the exposed fingers was observed. The author reports that using the VAC system may decrease the typical 2-3 week attachment period for such flaps by promoting wound granulation and vascularization.
This study compared outcomes of 120 burn patients who underwent either early excision and grafting (E&G) within 4-7 days, or delayed excision and grafting (D&G) within 1-4 weeks. Significant differences favored the E&G group: fewer culture-positive wounds, better graft take, shorter post-graft hospital stay, and no mortality. While early excision improves outcomes, the optimal timing requires further study. However, this study supports performing excision as early as possible when stabilization has occurred.

Electrosurgical units are commonly used in operating rooms to apply electrical energy for surgical purposes. The document reviews the biophysics of electrosurgery and potential mechanisms of injury, which can occur through direct application, insulation failure, or capacitive coupling. It concludes that thorough understanding of electro surgery fundamentals by the operating room team is essential for patient safety and recognizing complications, and newer hemostatic technologies may help decrease injury incidence.
This document proposes a device called E-VAC that combines electrical stimulation and vacuum-assisted closure therapy to treat pressure ulcers. It suggests that combining the two therapies may improve wound healing through a protocooperative relationship. The document outlines the design criteria for E-VAC, which include: improving healing time of stage 3 and 4 pressure ulcers, maintaining infection control, simultaneously applying negative pressure and electrical stimulation through a single device, and being no more complicated to apply than existing therapies. A proposed design is described involving a polyurethane foam dressing connected to a vacuum pump and electrodes to deliver both therapies simultaneously through a single smart bandage.
This document describes a study evaluating the use of dynamic dermal approximation sutures for closing wounds following fasciotomy to treat compartment syndrome. The technique was applied to 12 patients and achieved wound closure in 75% of cases without need for skin grafting. Specifically, it closed all wounds in 6 patients who developed compartment syndrome due to contrast extravasation. The technique aims to provide early wound closure following fasciotomy in order to reduce complications compared to delayed closure or skin grafting. The results suggest this technique can successfully close uncomplicated fasciotomy wounds with minimal risk and good cosmetic outcomes.
In operating room the most hazardous devise used in a daily basis is diathermy.
A basic understanding of electricity is needed to safely apply electrosurgical technology for patient care.
Diathermy uses high frequency electric current to generate heat for surgical purposes like coagulation and cutting. While an invaluable surgical tool, it can pose fire and burn hazards if safety precautions are not followed. The main causes of surgical fires are ignition sources like electrosurgical units interacting with fuels like alcohol-based skin preps in the presence of an oxidizer like oxygen. Proper use of diathermy requires checking equipment, applying return electrodes correctly, allowing preps to dry, and avoiding flammable anesthetic gases. Following safety protocols can minimize risks while allowing diathermy to continue enabling beneficial effects in surgery.
This document discusses burns, including their definition, classification, causes, clinical features, and management. Burns are injuries caused by heat, flames, scalds, or chemicals and can range from superficial first degree burns to full thickness third degree burns that destroy all skin layers. Burn management involves initial first aid, medical care including fluids and antibiotics, surgical procedures such as skin grafting, and nursing care like wound dressing and pain management to prevent complications and promote healing.
The document provides information on using the Hyfrecator 2000 for electrosurgery. It compares the Hyfrecator to other electrosurgery methods like electrocautery and cryotherapy.

This study investigates exposure of the human body to electromagnetic fields from induction cooktops, both professional and domestic models. Magnetic field measurements were taken from 13 professional cooktops and 3 domestic cooktops to develop a numerical model. Current density induced in anatomical models of adults, children, pregnant women, and fetuses was then simulated. While most cooktops complied with public exposure limits at 300 mm as required by standards, many exceeded limits at closer distances and some exceeded even occupational limits. The maximum current density in users was found to significantly exceed the basic restrictions for public exposure set by ICNIRP, reaching occupational levels. Exposure of children's brains and fetal tissue was also found to exceed public exposure limits in some

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Cautery Burns

Introduction
Over the last century electrocautery has emerged as
an imperative adjunct to surgery across the entire range of
surgical disciplines. A diathermy machine converts elec-
tricity of the main supply (240V; 50 Hz) into high fre-
quency current (>100,000 Hz) to minimize the risk of elec-
trical shocks. In monopolar mode, the current from the
diathermy enters the patient through the active electrode
and exits through the grounding pad. In bipolar mode the
current passes between the two prongs of the electrode
without any significant flow through the patient and there
is no need for the grounding pad.
Bovie deserves acknowledgement for his outstanding
pioneering role in designing the first surgical diathermy
machine in 1928. Since then cautery has been increasing-
ly employed in surgery for cutting and coagulating, en-
suring efficient haemostasis during surgery.1-4
It has be-
come popular even for making skin incisions, given its
quickness, effective haemostasis and associated lesser pain
and minimal scarring.
5,6
Although most of the newest diathermy machines are
largely safe, the electric fields they generate are still in-
herently hazardous for the patient, operating surgeons, and
theatre staff. They can cause burn injury, electrocution, op-
erating room fire, smoke inhalation, and gene mutation.
5-7
Several newer electromedical devices, laparoscopic
diathermy and fiberoptic retractors are now emerging, and
these pose the same hazards as cautery. The fire triangle
consists of three elements necessary for initiation of an op-
erating room fire, i.e. a heat source (e.g. electrocautery
unit, laser), fuel (i.e. body tissues), and an oxidizer (sup-
plemental oxygen).
7-9
Iatrogenic cautery burns during surgery may result from
one of the following four mechanisms: direct contact burns
from the active electrode resting on the patient’s skin or
contacting the operating staff; burns at the site of the ground-
ing electrode; burns resulting from electrode heating of
pooled solutions such as spirit; and burns occurring outside
the operative field as a result of circuits generated between
the active electrode and an alternate grounding source.10-16
We report our experience with three patients who pre-
sented to us with full-thickness deep burns following haem-
orrhoidectomy, surgery for coronary artery bypass graft-
ing, and orthopaedic surgery. Our aim is to prompt aware-
ness among the surgical staff regarding this avoidable haz-
ard and promote a proactive attitude on the part of the sur-
gical team towards prevention.
Case histories
Case I. A 21-yr-old lady presented to our outdoor de-
partment with a one-week history of haemorrhoidectomy
under spinal anaesthesia in lithotomy position. The oper-
ating time was 1 hour. The grounding pad had been ap-
plied over the distal thigh on posterolateral aspect. The
grounding pad was found to have a deep burn after re-

SUMMARY. This brief report highlights three cases of iatrogenic electrocautery burns with review of the relevant published lit-
erature. The aim is to prompt awareness among surgeons and theatre staff regarding this avoidable hazard associated with the equip-
ment frequently used for the purpose of electrocautery. This may serve as a reminder to professionals to be cautious about the pit-
falls that lead to such preventable injuries.

covery from surgery (Figs. 1, 1A). Our consultation was
sought, and the patient was managed with excision and
split thickness skin graft.
Case II. A 51-yr-old male who had triple vessel dis-
ease of the coronary arteries underwent successful coro-
nary artery bypass grafting. His cardiac surgery proceed-
ed uneventfully. The operating time was 3.5 hours. The
grounding pad had been applied over the lower back, which
was discovered to have a deep burn after recovery from
surgery (Fig. 2). Our consultation was sought and the pa-
tient was managed with hydrogel dressings. Once dis-
charged from the cardiac surgery unit, he was followed as
an out-patient. He was advised to have wound closure, but
did not consent to another surgical operation continued
with conservative management and healed by secondary
intention after two months.
Case III. A 32-yr-old lady presented through the out-
patients department with a two-week history related to a
wound on her lower back. She had undergone orthopaedic
surgery for a fractured radius and ulna under general anaes-
thesia. Her surgery had lasted for two hours and the ground-
ing pad had been applied over the lower back (Fig. 3).
Our consultation was sought, and the patient was managed
with excision and split-thickness skin graft.
Discussion
Use of monopolar cautery and improper placement of
the grounding electrode constituted the cause of electro-
cautery burns in our cases. While modern electrodes have
been designed to minimize this complication, such burn
injuries still continue to inflict patients and are often deep.17-
23
Ignorance or negligence regarding standard safety pro-
tocols often underlies such mishaps. In a relatively recent
attempt to abolish this complication, a noncontact electro-
surgical grounding device has been developed, but its long-
term safety benefits are yet not proven.
22
In all our patients, the cause of burns was faulty ap-
plication of the grounding pad, which failed to have good
contact with the patients’ skin. When the grounding pad
is loose, this may cause heat generation and sparking at
the contact site, without providing an appropriate exit for
the current to pass safely through the circuit. Several meas-
ures can be adopted to prevent these mishaps. The oper-
ating surgeon himself should have a proactive attitude and
personally ensure that the grounding pad is adequately ap-
plied with firm contact to the skin over an adequate sur-
face area. Preferably it should be secured to the skin with
a crepe bandage. An area of at least 70 cm
2
of firm skin-
pad contact should be ensured. Special care should be ex-
ercised to re-check the position of the pad if the patient’s
position is changed intra-operatively. One may employ the
newer grounding pads with adhesive properties that firm-
ly attach them to skin. The diathermy machine’s active
alarm system will also help to limit the extent of the re-
sultant burn injury. If a bipolar cautery is employed the
risk of grounding pad burns can be eliminated altogether.
All our patients had deep burns. One patient who had
cardiac surgery was managed conservatively with dress-
ings while two had resurfacing of their wounds with split-
thickness skin grafts. Sanders et al.
24
reported a case of
deep burns from the grounding pad in a patient undergo-
ing shoulder arthroscopy. The literature has reported sev-
eral other cases of cautery burns occurring during differ-
ent various surgical procedures such as cardiac surgery,
orthopaedics, and neurosurgical procedures.
Most of these were deep burns and required plastic
surgical interventions.
25-27
Mundinger et al.
10
reported a case of forehead burns
in a patient with titanium plates in her skull bones pre-
viously implanted as part of treatment for her skull anom-
alies. The grounding pad was placed on the lateral thigh,
however burns occurred at her forehead as she was posi-
tioned prone and circuit generated between the active elec-
trode and an alternate grounding source (i.e. indwelling
hardware). This case exemplified the alternate-site or ca-
pacitative coupling burns wherein an aberrant intra-oper-
ative circuit is generated by equipment contacting the

body of the patient. This results in burns at sites of con-
tact remote from the operative field and the normal ground-
ing pad. Such injuries may occur on areas of un-insu-
lated surgical table contacting the patient, electrocardio-
graphic leads, temperature probe insertion sites, and sites
of placement of various other monitoring devices.
28-31
There is a recent growing recognition of the added
danger posed by the combination of supplemental oxy-
gen and electrocoagulation in facial surgery. Engel et al.
8
have reported three such patients sustaining burn injuries
while undergoing facial plastic surgery under conscious se-
dation and supplemental oxygen. One prudent way is to
avoid using supplemental oxygen without proper endotra-
cheal intubation altogether as the oxygen-enriched atmos-
phere contributes to the fire as an oxidizer.
2,8,32-35
The use of alcohol and spirit based skin preparation
solutions is another risk factor for fires and burn injuries
in the operating room. The solution, if not evaporated be-
fore employing the cautery, will lead to fire and burn in-
jury. The electrosurgical diathermy unit is the usual source
of heat to ignite the flammable substance, although lasers
and fiberoptic lights can also be potent heat sources. The
fuel is provided by alcohol-based prep solution, drapes,
sponges, and endotracheal tubes. In the presence of a high
oxygen environment, all of these substances can burst in-
to flames and burn intensely. When alcohol-based prep is
used and the patient is draped before the solution is com-
pletely dry, alcohol vapors can be trapped and channelled
to the surgical site or the solution wick may get into the
surrounding linen, where a heat source can ignite the
vapours.
11,30,31,36,37
When using alcohol-based skin prepara-
tions a few precautions should be strictly adhered to. The
surgeon must wait for at least 3 minutes for the solution
to evaporate and the skin is wiped with a cotton swab be-
fore draping the surgical site; shaving the skin to prevent
pooling of solution in the hair; effectively drape the patient
with a clear plastic adhesive drape to prevent collection of
flammable vapors beneath the drapes. The best policy is to
avoid these flammable substances and use the much safer
solutions of povidone iodine and chlorhexidine.
An electrocautery burn is a medical error which also
has medicolegal and ethical implications. There is a long
list of such errors, from simple misdiagnosis to more se-
rious harm that may culminate in the patient’s death. Such
errors may emanate from negligence or system failure. Un-
fortunately such errors continue to occur in every part of
the world. Ideally the professional staff and hospital ad-
ministration concerned should ensure patient safety by pre-
venting such mishaps and compensate for the harm that
ensues to the patients.38-41
Reporting such errors is impera-
tive as this will ensure safer management of future patients
by sensitizing the professionals involved, leading to the
adoption of preventive strategies.
42-45
Conclusion
We conclude by reiterating the fact that as long as we
continue to use the available conventional unipolar elec-
trocautery, the hazard of burns to patients particularly at
the grounding pad site must be borne in mind. The oper-
ating surgeon should be mindful of the risks involved and
be proactive to ensure the patient’s safety.

general anaesthesia and sustained iatrogenic burns in the grounding
pad site on her lower back.

but continued to suffer from cautery burn for two months.
RÉSUMÉ. Ce bref rapport met en évidence trois cas de brûlures iatrogènes provoquées par l’électrocautère, avec une revue de la
littérature pertinente. L’objectif est d’inciter davantage la sensibilité des chirurgiens et du personnel du théâtre opératoire au sujet
