Intraoperative care
Intraoperative chapter review
Question | Answer |
---|---|
What is the intraoperative period? | This begins when the patient enters the surgical suite and ends at the time of transfer to the postanesthesia reconvery are, same-day unit, or ICU |
What are the main concerns during the intraop period? | Safety and advocacy |
What are some of the “at risks” in the OR? | Risk for infection, impaired skin integrity, increased anxiety, altered body temp, and injury related to positioning and other hazards |
Why is nursing care during the intra op period critical? | b/c the patients physical needs, spiritual needs, comfort, safety, dignity, and psychological status depends on the periop nurse |
Surgeon | Is a physician who assumes responsibility for the surgical procedure and any surgical judgement about the patient |
Surgical assistant | Might be another surgeon or PA, CRN, CRNFA, or surgical tech, they work under the direction of the surgeon and within the legal scope of practice for each state, the assistant may hold refractors, suction the wound, cut tissue, suture, and dress wounds |
Anesthesiologist | This is a physician who specializes in giving anesthesic agents |
CRNA | This is a RN with additional education and credentials who delivers anesthetic agents under the supervision of an anesthesiologist, surgeon, dentist, or podiatrist |
What areas does the anesthesia provider need to be monitored during surgery? | Level of anesthesia, cardiopulm functions, vital signs, and I&O |
OR nurse | This person used clinical decision-making skills, deveolpe a plan of nursing care, and coordinates care delivery to patient and their families |
Holding area nurse | They coordinate and manages the care while the patient is in this area. Greeting the pt, reviewing records, and preop checklist, verify consent signed, and document risk assessment |
Circulating nurse | coordinate, oversee, and are involved in the pt care in the OR, coordinate activities for the OR- all supplies, blood, diagnostic supports are available and inspected. Helps maintain count of scrubs, instruments, sharps, amt of irrigated fluids and drugs |
Throughout surgery, the circ nurse has what responsibilities? | Monitor traffic, assesses the amt of urine/blood loss, reports findings, all sterile fields are maintained by staff, anticipates needs of pt and team, communicated pt status with family, document care, events, interventions and findings |
Scrub nurse/operating rooms tech, surgical tech, certifies surg tech (CST) | They set up sterile field, drape the pt, and hand sterile supplies/equipment/instruments to surgeon. Must have knowledge of procedures, to pick correct tools. Helps maintain count of scrubs, instruments, sharps, amt of irrigated fluids and drugs |
Specialty Nurse | Particular type of surg (ortho, cardiac, ophthalmologic). They are responsible for care specific to patients needing that type of surg. Maintains, recommends equip, instruments, and supplies. |
Laser specialty nurse or laser nurse coordinator | Specially trained in the use, care and maintenance of the laser |
What does laser mean? | Light Amplification by the Stimulated Emission of Radiation- it gives off a high powered beam of light that cuts tissue |
Who keeps count of all that is used in surgery from before the surgery to immediately before complete skin closure? | Scrub and circulating nurse |
What are the 3 zones of the OR? | Unrestricted, semi-restricted and restricted |
Define- minimally invasive surgery (MIS) | This involves making one or more small incisions in the area of the surgery and placing an endoscope through the opening |
What types of surgeries are preferred for MIS? | Cholecystectomy, cardiac surgery, splenectomy and spinal surg |
Define- endoscope | This is a tube that allows viewing and manipulating on internal body areas. Some with magnification views. These are rigid, semirigid, or flexible |
What are the different endoscopes and the uses? | laparoscopes- abd surg, arthroscopes- joint surg, and ureteroscopes- UT surg |

Define- general anesthesia | a reversible LOC induced by inhibiting neuronal impulses in several areas of the CNS. Depressing the CNS. |
How is general anesthesia achieved? | with a single agent or combo of agents. Anesthesia depressed the CNS, resultsing in analgesia, amnesia and unconsciousness, with loss of muscle tone and reflexes. Pt is unaware |
When is general anesthesia most given? | surg of the head, neck, upper torso, and abd. And when patient cannot cooperate |
Define- analgesia | pain relief or pain suppression |
Define- amnesia | memory loss of the surgery |
Define- emergence | speed of recovery from anesthesia |
What does emergence depend on? | it deoends on the type of anesthetic agent,length of time the patient is anesthetized, and whether a reversal agent is used |
What common effect during emergence/recovery does the patient incounter? | retching, vomiting, and restlessness. In recovery shivering, rigidity and light cyanosis- due to the temporary changes in the body;s temp control |
What are the 4 stages of induction of general anesthetics? | Stage1-analgesia and sedation, relaxation; stage2- excitement, delirium; stage3-operative anesthesia, surgical anesthesia; stage4 danger |
What happens in stage 1 of general anesthesia? | Begins with induction and ends with loss of consciousness, Pt feels drowsy and dizzy, reduced sensation to pain, and is amnesic. Hearing is exaggerated. |
What happens in stage 2 of general anesthesia? | Begins with LOC and ends with relaxation, regular breathing, and loss of the eyelid reflex. Irregular breathing, increased muscle tone, and involuntary movement of the extremities, is susceptible to external stimuli. Laryngospasm or vomiting. |
What happens in stage 3 of general anesthesia? | Begins with muscle relaxation and ends with loss of reflexes and depression of vital functions, jaw is relaxed, and breathing is quiet/regular, cannot hear, sensations are lost. |
What happens in stage 4 of general anesthesia? | Begins with depression of vital functions and ends with respiratory failure, cardiac arrest, and possible death. Respiratory muscles are paralyzed; apnea occurs, pupils are fixed/dilated. |
What are the ADV of General inhalants anesthetics? | ADV: Most controllable method, Induction and reversal accomplished with pulmonary ventilation,Few side effects |
What are the DISADV of General inhalants anesthetics? | DIS: Must be combination with other agents for painful/prolonged procedures, limited muscle relaxant effects, Postoperative nausea and shivering common, Explosive |
What are the ADV of General Intravenous anesthetics? | ADV: Rapid and pleasant induction, Low incidence of postoperative nausea and vomiting, Requires little equipment |
What are the DISADV of General Intravenous anesthetics? | DIS: Must be metabolized and excreted from the body for complete reversal, Contraindicated in presence of hepatic or renal disease Increased cardiac and respiratory depression, Retained by fat cells |
What are the ADV of General Balanced anesthetics? | ADV: Minimal disturbance to physiologic function, Minimal side effects, Can be used with older and high-risk patients |
What are the DISADV of General Balanced anesthetics? | DIS: Drug interactions can occur, Pharmacologic effects on the body may be unpredictable |
What are the ADV of Regional or Local anesthetics? | ADV: Gag and cough reflexes stay intact, Allows participation and cooperation by the patient, Less disruption of physical and emotional body functions, Decreased chance of sensitivity to the agent, Decreased intraoperative stress |
What are the DISADV of Regional or Local anesthetics? | DIS: Difficult to admin to an uncoop/upset pt, No way to control agent after admin, Absorbs rapidly into blood and causes cardiac depression or OD, Increased Nerv sys stimulation (OD), Not good for extensive surg b/c of the amt need to maintain anesthesia |
What are the ADV/DISADV of Cryothemia anesthetics? | ADV: Reflexes remain intact, Decreases chance of adverse reactions, Decreased intraoperative stress; DIS: No way to control depth of anesthesia, Not used in long or extensive procedures, May not be appropriate for an anxious patient |
What are the ADV/DISADV of hypnosis/hypnoanesthesia? | ADV: Reflexes remain intact; DIS: Requires patient cooperation, Requires special training |
