* **Body Identification:** Confirm the identity of the deceased using identification tags and documentation.
* **Positioning:** Carefully position the body on the embalming table, ensuring proper alignment and support. Elevate the head and shoulders to facilitate drainage.
* **Washing and Disinfection:** Thoroughly wash the body with a germicidal soap and water. Disinfect all orifices (mouth, nose, ears, rectum, and genitalia).
* **Shaving:** Shave the face and neck as needed, following the natural hair growth pattern.
* **Feature Setting:** Close the eyes using eye caps or cotton. Close the mouth using a needle injector, sutures, or a mouth former. Ensure a natural and relaxed facial expression.
* **Pre-Embalming Analysis:** Assess the condition of the body, including the presence of rigor mortis, livor mortis, edema, or other postmortem changes. This assessment will inform the selection of embalming fluids and techniques.

**V. Arterial Embalming: Step-by-Step Procedure**

Arterial embalming involves injecting embalming fluid into the arterial system to preserve the tissues.

1. **Artery Selection:** The common carotid artery is a commonly used artery due to its accessibility. Other options include the femoral artery, axillary artery, and brachial artery. The choice of artery depends on factors such as the condition of the body and the location of any trauma or obstructions.
2. **Incision:** Make an incision along the selected artery. The length and placement of the incision will depend on the chosen artery. For the common carotid artery, a small incision is typically made along the anterior border of the sternocleidomastoid muscle.
3. **Artery Isolation:** Carefully dissect and isolate the artery and vein. Use blunt dissection to avoid damaging surrounding tissues. Place aneurysm hooks or ligatures around the artery and vein to control blood flow.
4. **Arterial Cannulation:** Insert an arterial tube (cannula) into the artery, directing it towards the heart. Secure the cannula with a ligature.
5. **Venous Drainage:** Insert a drainage instrument (e.g., drain tube or forceps) into the corresponding vein. Direct the drainage instrument towards the heart. Secure the instrument with a ligature. Alternatively, if the jugular vein is used in conjunction with the carotid artery, a slit can be made in the vein without the use of a drainage device. This allows for better fluid exchange and less distention.
6. **Embalming Fluid Preparation:** Prepare the embalming fluid solution according to the manufacturer’s instructions and the pre-embalming analysis. Consider factors such as the deceased’s weight, condition, and the desired level of preservation. Typical solutions involve a mixture of formaldehyde-based arterial fluid, water, and modifying agents (humectants, buffers, etc.).
7. **Injection and Drainage:** Turn on the embalming machine and begin injecting the embalming fluid into the arterial system. Simultaneously, monitor the venous drainage. The goal is to achieve a balanced injection and drainage rate, ensuring that the tissues are properly saturated with embalming fluid without causing excessive swelling.
8. **Distribution and Diffusion:** Observe the distribution and diffusion of the embalming fluid throughout the body. Look for signs of fluid reaching the extremities, such as clearing of livor mortis and firming of tissues. Massage the limbs to aid in distribution.
9. **Pressure and Rate of Flow:** Regulate the pressure and rate of flow of the embalming machine to optimize fluid distribution and minimize swelling. Start with a low pressure and gradually increase it as needed. The ideal pressure and rate of flow will vary depending on the condition of the body.
10. **Intermittent Drainage:** Periodically stop the injection and allow for intermittent drainage. This helps to prevent swelling and improve fluid distribution.
11. **Completion of Arterial Embalming:** Continue the injection and drainage process until a sufficient volume of embalming fluid has been injected and the tissues are adequately preserved. This may take several hours, depending on the condition of the body. Signs of completion include firming of tissues, clearing of livor mortis, and a uniform distribution of embalming fluid.
12. **Removal of Cannulas and Instruments:** Once arterial embalming is complete, carefully remove the arterial tube and drainage instrument. Ligate the artery and vein securely to prevent leakage. If the vessels are fragile, consider using tissue adhesive in addition to ligation.
13. **Suturing:** Suture the incision using a suitable suture pattern. Ensure that the incision is closed tightly and that there are no gaps or openings.

**VI. Cavity Embalming: Step-by-Step Procedure**

Cavity embalming involves aspirating fluids from the body cavities and injecting cavity fluid to preserve the internal organs.

1. **Trocar Insertion:** Insert a trocar into the abdominal cavity. The standard point of entry is typically two inches to the left and two inches superior to the umbilicus. Follow the trocar guides to ensure proper placement and avoid damaging major organs. Trocar guides are imaginary lines to help embalmers avoid puncturing vital organs.
2. **Aspiration:** Aspirate all fluids and gases from the thoracic, abdominal, and pelvic cavities using the trocar and aspirator. Pay particular attention to the lungs, stomach, intestines, and bladder. Continue aspiration until no further fluids can be removed. A complete aspiration will help prevent purge and odors.
3. **Cavity Fluid Injection:** Inject cavity fluid into each of the body cavities using the trocar. The amount of cavity fluid injected will depend on the size of the body and the degree of decomposition. A typical adult requires approximately 32-48 ounces of cavity fluid.
4. **Trocar Removal and Closure:** Remove the trocar and seal the trocar point using a trocar button or sutures. This will prevent leakage of fluids and gases.
5. **Re-Aspiration (Optional):** In cases of advanced decomposition or edema, re-aspiration may be necessary several hours after the initial cavity embalming. This will help to remove any additional fluids that have accumulated in the body cavities.

**VII. Supplemental Embalming Techniques**

In addition to arterial and cavity embalming, several supplemental techniques may be used to address specific preservation challenges.

* **Hypodermic Embalming:** Injecting embalming fluid directly into tissues that are not adequately reached by arterial embalming. This is useful for treating areas such as the face, neck, hands, and feet.
* **Surface Embalming:** Applying embalming gels or packs to the surface of the body to preserve and deodorize tissues. This is useful for treating skin lesions, ulcers, or areas of decomposition.
* **Arterial Co-Injection:** Injecting a solution containing humectants and water conditioners along with arterial fluid, particularly useful in cases of dehydration or renal failure.

**VIII. Post-Embalming Procedures**

* **Washing and Drying:** Thoroughly wash and dry the body to remove any traces of embalming fluid.
* **Hair Styling:** Style the hair according to the family’s wishes or a pre-arranged style.
* **Cosmetics:** Apply cosmetics to create a natural and pleasing appearance. Use appropriate colors and techniques to conceal discoloration and imperfections.
* **Dressing:** Dress the body in the clothing provided by the family or as instructed.
* **Casketing:** Place the body in the casket, ensuring proper positioning and presentation.
* **Room Cleanup:** Clean and disinfect the embalming room and all equipment. Dispose of waste materials according to regulations.

**IX. Safety Precautions**

Embalming involves exposure to hazardous chemicals and infectious agents. It is essential to follow strict safety precautions to protect yourself and others.

* **Personal Protective Equipment (PPE):** Always wear appropriate PPE, including gloves, mask, gown, face shield, and eye protection. Change gloves frequently and wash hands thoroughly after removing them.
* **Ventilation:** Ensure adequate ventilation in the embalming room to minimize exposure to formaldehyde fumes. Use a local exhaust ventilation system if available.
* **Formaldehyde Monitoring:** Regularly monitor formaldehyde levels in the embalming room to ensure compliance with OSHA standards.
* **Spill Control:** Have a spill kit readily available and follow proper procedures for cleaning up spills of embalming fluids or other hazardous materials.
* **Sharps Safety:** Use extreme caution when handling needles, scalpels, and other sharp objects. Dispose of sharps in designated sharps containers.
* **Infection Control:** Follow strict infection control procedures to prevent the spread of infectious diseases. Properly disinfect all surfaces and instruments after each use. Consider the deceased as potentially infectious, regardless of their known medical history.
* **Waste Disposal:** Dispose of embalming waste according to local, state, and federal regulations. This may include incineration, autoclaving, or other approved methods.
* **Training and Education:** Participate in regular training and education programs to stay up-to-date on the latest safety procedures and embalming techniques. Knowledge of SDS (Safety Data Sheets) for all chemicals used is critical.

**X. Common Embalming Challenges and Solutions**

* **Edema:** Reduce edema by using hypertonic arterial fluids, restricted drainage, and elevation of the extremities. Consider using edema reducing co-injection fluids.
* **Dehydration:** Rehydrate tissues by using humectant-rich arterial fluids and pre-injection fluids. Avoid using strong concentrations of arterial fluid.
* **Jaundice:** Use jaundice arterial fluids that contain bleaching agents to help reduce discoloration. Consider using opaque cosmetics to conceal any remaining discoloration.
* **Decomposition:** Use strong arterial fluids and cavity fluids to control decomposition. Consider using supplemental embalming techniques such as hypodermic embalming and surface embalming. High index fluids are often necessary.
* **Vascular Obstructions:** Inject embalming fluid from multiple injection sites to bypass vascular obstructions. Use massage to help distribute the fluid around the obstructions.
* **Rigor Mortis:** Manually manipulate the limbs to break rigor mortis before embalming. Use pre-injection fluids to help relax the muscles.
