Monitoring, assessment and observation skills are essential in postoperative care. Nurses can support patients recovering from surgery and identify complications Show
AbstractPostoperative care is provided by peri-operative nurses. They are often experienced in a specialised area of surgery that requires specific care for the intervention performed. This article, the first in a two-part series, identifies the principles of postoperative nursing care. These remain reasonably consistent over the years but nurses must ensure they keep up to date with guidelines, policies and evidence-based practice.

IntroductionA report by the National Confidential Enquiry into Patient Outcome and Death identified a need for a UK-wide system that would enable health professionals to identify high-risk surgical patients easily and quickly and for their care to be managed appropriately (NCEPOD, 2011). This was accompanied by a number of other recommendations:
Immediate postoperative carePostoperative patients must be monitored and assessed closely for any deterioration in condition and the relevant postoperative care plan or pathway must be implemented. The NCEPOD (2011) report found that patients whose condition was deteriorating were not always identified and referred for a higher level of care. Patients should be made as comfortable as possible before postoperative checks are performed. Postoperative patients are at risk of clinical deterioration, and it is vital that this is minimised. Knowledge and understanding of the key areas of risk and local policies will help reduce potential problems (National Patient Safety Agency, 2007; National Institute for Health and Clinical Excellence, 2007). Track and trigger or early warning systems are widely used in the UK to identify deteriorating patients. These have been adapted by trusts for adults and children and are based on the patient’s pulse and respiratory rate, systolic blood pressure, temperature and level of consciousness. Additional monitoring may include pain assessment, capillary refill time, percentage of oxygen administered, oxygen saturation, central venous pressure, infusion rates and hourly urine output. The National Early Warning Score (NEWS) was developed by a working party to provide a national standard for assessing, monitoring and tracking acutely and critically ill patients (not for use with children under 16 years or in pregnancy); the intention was that trusts would use it to replace their locally adapted early warning systems (Royal College of Physicians, 2012). Like other early warning systems, NEWS has six physiological parameters:
The system also includes a weighting score of two, which is added if the patient is receiving supplemental oxygen via a mask or nasal cannulas. When assessing the postoperative patient using NEWS, it is vital that the patient is observed for signs of haemorrhage, shock, sepsis and the effects of analgesia and anaesthetic. Patients receiving intravenous opiates are at risk of their vital signs and consciousness levels being compromised if the rate of the infusion is too high. It is therefore imperative that the patient’s pain control is managed well, initially by the anaesthetist and then the ward staff and pain team or anaesthetist, to ensure that the patient has adequate analgesia but is alert enough to be able to communicate and cooperate with clinical staff in the postoperative period. Many trusts have yet to implement NEWS, although it is beginning to be taught in pre-registration nursing programmes. Student nurses frequently perform postoperative observations under the supervision of a nurse; it is reassuring that they receive some insight and education as recommended by NCEPOD (2011). Vital signsVital signs should be performed in accordance with local policies or guidelines and compared with the baseline observations taken before surgery, during surgery and in the recovery area. Nurses should also be aware of the parameters for these observations and what is normal for the patient under observation. When assessing patients’ recovery from anaesthesia and surgery, these observations should not be considered in isolation; the nurse should look at and feel the patient. This also applies to children and should include observation of other signs and symptoms, for example abdominal tenderness or poor urine output, which could indicate deterioration (Royal College of Nursing, 2011). The RCN (2011) provides guidance on vital signs performed post-operatively on children. Many trusts now insist that vital signs are performed manually to provide more accurate recording and assessment. All vital signs and assessments should be recorded clearly in accordance with guidelines for record keeping (Nursing and Midwifery Council, 2009). Handheld personal digital assistants (PDAs) are used at some trusts to store track and trigger data and calculate early warning scores, which can be accessed by the clinical and outreach teams. When a patient’s condition is identified as deteriorating, this information can be passed verbally to appropriate health professionals using the Situation, Background, Assessment and Recommendation (SBAR) tool advocated by the NHS Institute for Innovation and Improvement (2008) (Box 1).

Airway and respirationsRespiratory rate and function is often the first vital sign to be affected if there is a change in cardiac or neurological state. It is therefore imperative that this observation is performed accurately; however, studies show it is often omitted or poorly assessed (NPSA, 2007; NCEPOD, 2005). Nurses should observe and record the following:
Oxygen therapyOxygen is administered to enable the anaesthetic gases to be transported out of the body, and is prescribed when patients have an epidural, patient-controlled analgesia or morphine infusion. Nurses should ensure and record the following:
Pulse oximetryOxygen saturation should be above 95% on air, unless the patient has lung disease, and maintained above 95% if oxygen therapy is prescribed to prevent hypoxia or hypoxaemia. An abnormal recording may be due to shivering, peripheral vasoconstriction or dried blood on the finger. Nurses should ensure that:
Heart rate, blood pressure and capillary refill timeThe following should be checked and recorded:
Particular attention should be paid to the systolic blood pressure as a lowered systolic reading and tachycardia may indicate haemorrhage and/or shock, although initially the blood pressure may not drop and will remain within normal limits as the body compensates. Tachycardia may also indicate that the patient is in pain, has a fluid overload or is anxious. Hypertension can be due to the anaesthetic or inadequate pain control. Body temperatureChildren, older adults and patients who have been in theatre for a long period are at risk of hypothermia. Shivering can be due to anaesthesia or a high temperature indicative of an infection, while a drop in temperature might indicate a bacterial infection or sepsis. Patients’ temperature should be monitored closely and action taken to return it to within normal parameters.
Level of consciousnessPostoperative patients should respond to verbal stimulation, be able to answer questions and be aware of their surroundings before being transferred to the ward and throughout the postoperative period. A change in the level of consciousness can be a sign that the patient is in shock. The AVPU scale (Box 2) is appropriate for assessing consciousness in adults, children and young people unless they have had neurosurgery (RCN, 2011). Box 2. AVPU scale
Fluid balanceThe NCEPOD (2011) found, in 30% of patient data reviewed, there was insufficient recording of postoperative fluid balance. Nurses should observe/undertake and record on the fluid balance chart the following:
Intravenous infusionsThe RCN (2010) and Health Protection Scotland (2012) recommend that peripheral venous catheters (PVC) are checked daily as a minimum, and consideration given to removing any PVC that has been in situ longer than 72 hours (Health Protection Scotland, 2012) or 72-96 hours (Department of Health, 2011). A phlebitis scale can be used to help assess the PVC site; the Visual Infusion Phlebitis Scale (Jackson, 1998) is frequently used and recommended by the RCN (2010). These national guidelines should be used as resources in caring for PVCs. The following should be checked and recorded:
ConclusionThe postoperative healthcare team is under constant pressure to discharge patients quickly. This can lead to vital signs being missed and result in a delay in recovery. Patients can be discharged quickly only when they do not experience any post-operative complications, many of which can be avoided or identified with correct and thorough monitoring of signs and symptoms. All health professionals must continually update their theoretical knowledge and clinical skills; those working in post-operative care can do this by relying less on electronic equipment and developing their ability to combine the use of assessment tools with good observational skills; feeling, listening for abnormal sounds and closely observing their patients. Part 2 of this series, to be published in next week’s issue, discusses postoperative pain control and patients’ care up to discharge from hospital. Key points

Neurological Assessment (AVPU, Michigan sedation score or formal GCS as indicated) Pain Score. Assessment of Wound Sites / Dressings. Presence of drains and patency of same.
What are 3 priority assessments of the PACU nurse?The PACU nurse performs an immediate assessment of the patient's airway, respiratory, and circulatory status, then focuses on a more thorough assessment.
What is the assessment of a post operative patient?The first post-operative assessment should take place following a patient's return from theatre. This acts as a baseline against which the patient's condition can be assessed at a later date and identifies any problems that may have occurred on transfer from the operating department.
