Surgical Nursing: Pre-Operative, Intra-Operative, and Post-Operative Care

Pre-Operative Phase

The nursing responsibilities in the pre-operative phase of surgery begin with comprehensive patient screening. This assessment includes blood work and laboratory tests, history of previous surgeries, medication allergies, history of chronic illness, nutrition level, and dietary requirements before and after surgery. The nurse evaluates all current medications to identify any contraindications to surgery. In addition to physical preparation, the nurse must prepare the patient mentally, physically, and spiritually, and conduct patient teaching to ensure the patient is fully informed of their rights and surgical details. The nurse also serves as a witness to the signing of informed consent, a critical legal and ethical responsibility.

Pre-operative nursing requires thorough assessment of patient needs, which may include the need for information and education, comfort measures, and spiritual guidance. Patients may require bathroom access, may feel ill, or may benefit from calming techniques. The nurse addresses each individual need with compassion and professionalism.

The nurse must ensure the patient is physically and mentally ready for surgery. Specific duties typically include placing the patient on NPO (nothing by mouth) status, starting an intravenous line, prepping the skin and intestinal tract, and administering pre-operative medications. These tasks usually follow surgeon orders or facility guidelines. Critically, the nurse must confirm that the patient feels informed of their rights, well-educated about the procedure, and mentally, spiritually, and emotionally prepared for surgery.

Patient teaching is a major pre-operative nursing responsibility. Patients often experience anxiety about surgical outcomes and anesthesia effects, and may worry about how surgery will affect their daily lives. The nurse teaches the patient about the procedure to reduce post-operative worries and explains what anesthesia does to provide reassurance. Post-operative techniques such as deep breathing and coughing exercises are taught and practiced pre-operatively so the patient can begin them immediately after surgery. The nurse answers questions and helps the patient reach a state of comfort and confidence before entering the operating room.

Modern surgical suites typically measure 600 square feet and are strategically located near intensive care units specializing in the type of surgery performed. For example, cardiac surgery suites are positioned on the same floor as cardiovascular intensive care units. The surgical environment incorporates multiple safety features: sterile techniques are strictly maintained, HVAC systems provide excellent ventilation and temperature control to prevent airborne infections, and lighting is optimized for precision work.

Continuous patient assessment occurs throughout the intra-operative period. Monitoring vital signs continuously is essential so the surgical team knows the patient's condition at all times. Staff remain with the patient continuously, providing different types of care. Before surgery begins, the surgical team performs a "time-out," in which the patient is identified by name and medical record number, the surgical procedure is verified, and the correct surgical site is confirmed. This verification prevents wrong-site, wrong-patient, and wrong-procedure errors.

Intra-Operative Phase: Surgical Environment and Team Structure

The surgical team consists of several key members, each with distinct and essential responsibilities:

Performs the designated surgery in a surgically aseptic and safe manner, ensuring patient safety and well-being at all times.

Monitors the patient throughout surgery and selects medications appropriate for the specific patient prior to surgery. This provider remains with the patient after surgery until the airway is established and the patient is stable.

Dons sterile personal protective equipment and maintains sterility at all times. The scrub nurse provides the surgeon with instruments and equipment throughout the procedure, prepares the sterile working field before surgery begins, and anticipates the needs of other team members to provide them with equipment promptly.

Manages overall patient care in the operating room and protects patient safety and health needs. The circulating nurse controls the environment regarding cleanliness, temperature, lighting, and humidity. This nurse ensures patient rights are protected, monitors care quality, and coordinates activities among team members. The circulating nurse and scrub nurse together are responsible for accounting for all sponges and instruments at the close of surgery.

Works to create an optimal environment for surgical patients. Scrub technicians work under the scrub nurse's supervision, while circulating technicians work under the circulating nurse's supervision. Both assist in ensuring a sterile and safe surgical environment for patients and staff.

Intra-Operative Safety and Patient Management

Before surgery begins, the surgical team performs a strict hand scrub and dons personal protective equipment using established aseptic techniques. During the procedure, the team maintains all items within the sterile field, inspects packaging before opening to ensure sterility, and verifies that gowns and gloves remain sterile and are donned correctly. Team members are trained to know where their sterile field ends and how to avoid contamination. Scrubbed personnel pass each other back-to-back with hands held up to maintain the integrity of their sterile fields. Team members do not leave their working sterile field and do not allow unscrubbed personnel to enter the sterile zone.

The type of anesthesia used depends on the nature of the surgery. General anesthesia is used for larger and more serious procedures requiring unconsciousness and muscle relaxation. Regional anesthesia is used for specific body areas or when the patient cannot receive general anesthesia. Local anesthesia is typically topical and is reserved for minor procedures; it is not used for large or invasive surgery unless significant medical contraindications prevent general anesthesia.

Common surgical positions include the supine or dorsal recumbent position, in which the patient lies on their back. Trendelenburg position places the patient on their back with feet elevated higher than the head, while reverse Trendelenburg does the opposite with the head elevated above the feet. Lithotomy position involves placing both feet in stirrups with the lower back toward the end of the surgical table. Sitting, prone (lying on the stomach), and side-lying positions are also used depending on the surgical approach.

Several critical safety measures protect patients during intra-operative care. The surgical team performs instrument counts before and after surgery to prevent retained foreign objects. The circulating nurse ensures all surgical team members are practicing sterile technique. The "time-out" procedure is a vital safety practice that confirms the right patient, correct surgery, and correct surgical site before the incision is made.

The post-anesthesia care unit (PACU) provides a monitored environment for patients immediately after surgery. The goal of PACU care is to stabilize all vital signs within one hour to return them to normal ranges. This specialized unit allows for intensive observation during the critical early recovery period when patients are transitioning from anesthesia.
