55 Care of the intensive care unit patient in the pacu
Extended-Stay ICU Patients: Critically ill surgical patients who have recovered from anesthesia but need to stay in the PACU an extended or prolonged period of time because of the severity of illness or the need to be observed for complications.
Family Presence: Families are provided the opportunity to be present in the PACU with their loved one during life-threatening situations or at the end of life during cardiopulmonary resuscitation or codes.
Intensive Care Unit (ICU): A hospital setting where critically ill patients are provided nursing care.
Intensive Care Unit Boarders: Critically ill surgical patients who have recovered from anesthesia in the PACU. These patientshave been designated ICU status, but do not have an ICU bed and are boarding in the PACU.
Intensive Care Unit Overflow Patients: Patients who have undergone anesthesia for surgical procedures, have recovered in the PACU, and are awaiting transfer to the ICU or SICU.
Sepsis: A systemic response to infection.
Septic Shock: Sepsis that progresses to a state of inadequate tissue perfusion characterized by persistent hypotension despite adequate fluid resuscitation.
Surgical Intensive Care Unit (SICU): A hospital setting for critically ill surgical patients who need specialized pulmonary, renal, cardiovascular, neurologic, or postoperative monitoring.
Systemic Inflammatory Response Syndrome (SIRS): A systemic response to infection that involves the activation of the inflammatory response to include change in body temperature, elevated heart rate, respiratory rate, and white blood cell count.
The admission of intensive care unit (ICU) patients to postanesthesia care units (PACUs) is steadily increasing. In addition, the PACU also cares for another type of critically ill surgical patient population: ICU overflow patients, also known as ICU boarding patients. This terminology refers to a unique critical care patient population who recovers in the PACU and subsequently meets the PACU discharge criteria. However, these ICU patients are unable to be transferred because of the unavailability of inpatient ICU beds, subsequently theyremain in the PACU. This increase reflects a nationwide health care dilemma for emergency department and PACU patients who create a high demand for hospital beds. The American Society of PeriAnesthesia Nurses (ASPAN) Delphi Study identified ICU overflow patients and critical care competencies as the top research clinical, educational, and management priorities.1 Finally, these national patient safety priorities are strategic for ensuring safe, quality postanesthesia care to ICU patients and to the care environment.
Throughout the United States, divergent postanesthesia practices have existed in the provision of care for the surgical intensive care unit (SICU) patient. Operationally, ICU recovery must occur on a routine basis, regardless of prognosis or acuity in the appropriate care setting. Some PACU care of the postsurgical critical care patient may be sporadic or an exception to the norm. From a clinical and an administrative position, however, the PACU must provide the optimal standard of care to SICU patients.2 This chapter discusses the historic significance of critical care recovery, administrative issues in extended ICU care, innovative educational opportunities to ensure competent staff, and clinical strategies in caring for complex, high-acuity, critically ill patients. Because patient safety is essential in providing care to low-volume high-risk patients, complex and highly specialized ICU nursing care concentrates on neurosurgical, burn, and septic management during the postanesthesia period. Ultimately, postanesthesia care must be focused on providing competent care while preventing harm and keeping critically ill patients safe. Finally, when the SICU patient’s condition becomes life threatening, family presence during resuscitation is introduced as an end-of-life nursing intervention that promotes patient-family–centered care.
Historical significance of critical care recovery
During the late 1950s and early 1960s, ICUs emerged in hospitals for close monitoring of critically ill patients. Before that time, the critically ill postsurgical patients received care recovery rooms and inpatient wards. Critical care nursing was conceived to provide a setting in which the most acutely ill and injured patients received concentrated nursing care to enhance survival. Fifty years ago, ICUs were composed of a few specialized beds located at the end of or apart from an existing inpatient unit.3
Administrative issues
Financial constraints
The 1990s brought increased financial constraints on hospitals and increased competitiveness among hospitals. The focus in the 1990s on controlling costs led to a dramatic shift in the types of patients who were admitted to hospitals. Only the sickest patients were eligible for admission, and the length of stay was compressed to the shortest possible time.4 Although hospital population dropped, ICU patient volumes were steadily increasing. Hospital mergers and closings occurred in many cities. During this same time, two significant changes developed: (1) patient acuity of critically ill patients admitted to hospitals increased and (2) the shortage of ICU nurses prompted hospital administrators to close ICU beds. ICU bed closures have had a serious effect on PACUs. PACUs were naturally chosen for critical care overflow because the environment of care included highly technical monitoring and many critical care–educated nursing staff. In addition, the retention of staff in the PACU was much higher with fewer vacancies. This choice seemed the ideal answer to a complex problem. Consequently, the PACUs were increasingly requested for recovery of SICU patients, and in many hospitals the PACU was designated an ICU overflow unit until an ICU bed became available.
Management dilemmas
Nurse managers encounter numerous challenges between competing health care providers that relate to patient placement priority for ICU beds. These challenges are affected by decisions of senior administrators (e.g., chief operating officers, chief nursing officers, departmental medical officers of medicine and surgery, emergency or trauma physicians). The dilemmas faced by managers affect ancillary staff, families, patients, and the PACU staff nurses. The PACU manager is obligated to follow hospital policies and protocols. When senior administrators make decisions in the best interest of the hospital to keep the emergency departments and operating rooms open and to perform surgery for elective surgical cases regardless of high hospital population, the PACU becomes the relief valve for medical center admissions. Often the hospitalized patients who occupy beds in the ICU are not ready for transfer to a lower level of care. This gridlock has a domino effect on the PACU beds. Emergency department patients who need critical care may be given priority status for ICU beds, as may “code” call patients from inpatient units. Some ICUs actually hold beds open for potential code call situations. As the inpatient and ICU surgical cases are completed, they too compete for the PACU available beds. Complications arise if the PACU is still holding ICU patients from the day before or from earlier in the morning. Eventually, the operating room (OR) schedule may grind to a halt because of the ensuing gridlocked beds. In some hospitals, the OR continues to perform surgery on critical care patients, with admission of more ICU overflow patients to an already stressed PACU. These SICU patients become known as boarders, extended stay, or ICU overflow. Patients and families may voice intense dissatisfaction when the PACU is designated for ICU care.2
Recovery of the ICU patient who has an extended stay in the PACU may have serious physician repercussions. Anesthesia providers and surgeons become frustrated because they want to complete the elective surgical schedule. At times, their behaviors may strain relationships with the nurse manager. The lost surgical and anesthesia revenue can threaten the viability of the hospital if surgical cases continue to be delayed or cancelled. University hospitals also have graduate medical education and need to perform a required number of surgical or anesthesia cases per year to qualify for accreditation of the programs.
ICU patients emerging from anesthetic agents frequently request that their families visit in the PACU. Traditionally, PACUs have been considered large open units in which family visitation is severely limited because of other patients emerging from anesthesia. This type of policy can create intense conflict between the nurse and the family. Family expectations of a private room in which families can visit freely are not met. Furthermore, the family’s anxiety increases when the surgeon speaks about the critical nature of the surgery and the need to place the patient in the ICU. Families frequently worry and may perceive the ICU as a sign of impending death, based on past experiences or those of others.5 Understanding what critical care means to patients and families helps the nurse promote positive coping skills. Depending on the patient’s physical condition, effective communication with the ICU patient may be challenging. Barriers to communication can relate to emergence from anesthesia; the patient’s physical status; the existence of endotracheal tubes, which inhibit verbal communication; medications; or other conditions that alter cognitive function.5,6 The critical care patient’s anxiety can increase the stress response and further complicate the patient’s recovery. Patients may consider that they have a right to see and visit with their family and may find significant emotional support for well-being.
Managing and communicating with the ICU families in the PACU can be challenging. Depending on each patient’s diagnosis and acuity, the SICU patient’s family may be in crisis. If the patient’s condition is critical, the family may exhibit a high degree of stress, anxiety, blame, or other disturbing behaviors. Families may be emotional and act out or exhibit disruptive outbursts. The staff nurse may believe that one’s first duty is to provide care to the patient, not to the family. Time can pass quickly for the PACU nurse and not afford the family timely visits. Anxiety and worry mounts for the waiting family as a result of little or no communication and fear of the unknown. The PACU nurse needs to make a conscious effort to effectively communicate with the family in a manner that promotes coping, personal growth, and adaptation to the ICU patient’s critical condition (Box 55-1).7
BOX 55-1 PACU Nursing Actions for Families in Crisis
• Introduce the PACU Scope of Service.
• Assist the family in defining the SICU problem and condition.
• Aid in identifying sources of support for the family during hospitalization.
• Prepare the family for the PACU care environment, especially the effects of patients emerging from anesthesia, respect for other PACU patients, confidentiality, PACU equipment (e.g., cardiac monitors, ventilators, infusion pumps), and purpose of the equipment.
• Communicate with sincerity and compassion about the critical surgery or illness.
• Express confidence in the family’s ability to handle the situation.
• Try to understand the family’s perspective about the patient’s critical condition.
• Use a “one day at a time” approach and avoid encouraging the family to think of the what-ifs of the patient’s long-term outcome.
• Provide opportunities for the patient and family to make choices and feel useful.
• Guide the family in finding therapeutic ways to communicate with the patient.
• Ensure that the family receives information about significant changes in the patient’s condition.
• Allow the family the opportunity to call the PACU and speak to the nurse anytime.
• Advocate adjusting visitation hours to accommodate the family’s needs.

Staffing issues
The PACU nurses may express feelings of inadequacy related to critical care competencies. A PACU nurse may have no ICU nursing experience or outdated critical care experience. The critical care experience may have been generalized and not specific, or new technology may be foreign. Nurse-to-patient ratios may be exceeded for safe care. The PACU nurse may already be assigned one patient with simultaneous care for a newly admitted ICU patient with an unstable condition, and then family members (frequently numerous) want to be present and are upset because visitation is limited or not allowed. PACU nurses may find themselves in the midst of ethical situations that involve conflict between the needs of the ICU patient’s family members and the preferences of physicians and other health care providers. Consequently, this PACU environment may be chaotic and not conducive for healing. Visitors may perceive the PACU as a suboptimal environment for a loved one. When PACU nursing staff members perceive that safe patient care is becoming jeopardized or high risk, they should consult the nurse manager immediately.
As the nursing shortage in the United States has become more severe, placing ICU overflow patients in the PACU has become a standard of practice rather than being a series of isolated incidents.8 Reports from PACU nurses in different regions of the country have communicated unsafe practices. Postanesthesia nurses turned to their professional organization, the American Society of PeriAnesthesia Nurses (ASPAN), to voice their concerns about serious issues that affected the care they provided to recovering ICU patients in the PACU. The ASPAN Standards and Guidelines Committee conducted a special review of the evidence to identify current nursing practice issues. The following trends in the care of ICU patients in the PACU were identified:
1. Staffing requirements identified for phase I PACUs may be exceeded during times when PACUs are used for ICU overflow patients.2,6
2. The PACU Phase I nurse may be required to provide care to a surgical or nonsurgical ICU patient who has not been properly trained or has not had the required care competencies validated.2,6
3. Phase I PACUs may not be able to receive patients normally admitted from the operating room when staff is used to care for the ICU overflow patients.2,6
4. When the need to send ICU overflow patients to PACU Phase I does not occur regularly, both the PACU and the hospital management may not be properly prepared to handle the admission and discharge of PACU Phase I and ICU patients.2,6
ASPAN invited the American Association of Critical Care Nurses (AACN) and the American Society of Anesthesiologists to address the practice trend of caring for the ICU overflow patient in the PACU and to strategize to promote safe quality care regardless of where the SICU patient recovers from anesthesia. A collaborative position statement was promulgated by these three powerful specialty organizations (Box 55-2).2
BOX 55-2 Joint Statement on ICU Overflow
Background
1. Staffing requirements identified for phase I PACUs may be exceeded during times when PACUs are being used for ICU overflow patients.
2. The Phase I PACU nurse may be required to provide care to a surgical or nonsurgical ICU patient that the nurse has not been properly trained to care for or for which the nurse has not had the required care competencies validated.
3. Phase I PACUs may be unable to receive patients normally admitted from the operating room when staff is being used to care for ICU overflow patients.
4. Because the need to send overflow patients to the Phase I PACU does not occur regularly, both the PACU and the hospital management may not be properly prepared to deal with the admission and discharge of Phase I PACU and ICU patients.
Statement
1. The primary responsibility for Phase I PACU is to provide the optimal standard of care to the postanesthesia patient and to effectively maintain the flow of the surgery schedule.
2. Appropriate staffing requirements should be met to maintain safe competent nursing care of the postanesthesia patient and the ICU patient. Staffing criteria for the ICU patient should be consistent with ICU guidelines based on individual patient acuity and needs.
3. Phase I PACUs are by their nature critical care units, and as such, staff should meet the competencies required for the care of the critically ill patient. These competencies should include, but are not limited to, ventilator management, hemodynamic monitoring, and medication administration, as appropriate to the patient population.
4. Management should develop and implement a comprehensive resource utilization plan with ongoing assessment that supports the staffing needs for both the PACU and ICU patients when the need for overflow admission arises.
5. Management should have a multidisciplinary plan to address appropriate utilization of the ICU beds. Admission and discharge criteria should be used to evaluate the necessity for critical care and to determine the priority for admissions.

Orientation and basic critical care competencies
The first steps in planning an orientation to the PACU is the interview process and subsequent hiring of the nurse who is motivated to learn many new skills. In addition, the nurse who seeks to be professionally challenged on a daily basis inspires and motivates the critical care preceptor. The PACU should never be viewed as a place to wind down or retire, because nurses with that goal in mind are often immediately disappointed and dissatisfied with their new jobs. Many PACUs prefer to hire nurses with critical care experience. Medical-surgical nurses are also hired, provided that an adequate support system of nursing education exists during orientation and the length of orientation is such that the nurse without prior critical care experience has ample time to master the myriad new skills essential to the new role.
• Cardiac monitoring, rhythm interpretation, electrocardiogram interpretation
• Arterial blood gas interpretation
• Invasive monitoring equipment—the care and the assessment of the patient with:
Orientation should include the essentials of how to care for the patient who has all or some of the invasive monitoring equipment mentioned previously and how to assemble such equipment in preparation for insertion in the PACU. The PACU should have the necessary equipment readily available in the event that a patient’s condition worsens and invasive procedures are to be performed in the PACU.
Advanced critical care concepts
• Frequency of line and tubing changes
• Frequency of endotracheal tube rotation
• Frequency of ICP and cerebral perfusion pressure (CPP) measurements
• Frequency of measurements (e.g., cardiac outputs and indexes)
• Frequency of weighing the patient
• Frequency of chest radiographs, electrocardiograms, and laboratory studies
• Use of a continuous cardiac output type of PA catheter
• Use of warming devices for intravenous fluids or blood products
• Frequency of, and ability to perform and manage, the calculation of oxygen consumption, oxygen demand, oxygen extraction ratios, and other elements of oxyhemodynamic calculations (“oxy-calcs”)
• Various modes of mechanical ventilation, including pressure-controlled ventilation
• Use of and care of the patient with continuous infusions of muscle relaxants and twitch monitors
• Competency with protocols in the prevention of ventilatory-acquired pneumonia
• Competency/knowledge of protocols in the prevention of deep vein thrombosis
Creating A specialized critical care resource for the PACU
Many PACUs across the country care for ICU patients sporadically. This situation occurs when the hospital census is high or when a surgical emergency presents. Specialized critical care educational resources strategically provide the PACU nurse with expert advisors when the critical time arises. This resourceful method can be accomplished in several ways. First, the PACU can recruit expertise from the unit. Second, the nurse manager may elect to request key leadership staff to orient and become competent and proficient in managing the care of specific patient populations.
