Management of Obesity as a National Health Priority Area in the Perioperative Care of a Surgical Patient

Scenario

John is a 53-year-old male who presents with obesity, demonstrated by a body mass index (BMI) of 38, and a strangulated, painful right inguinal hernia. His past medical history includes obstructive sleep apnoea (OSA), which he manages at home using a Continuous Positive Airway Pressure (CPAP) device. Due to the severity of his condition, John is admitted for an emergency inguinal hernia repair requiring general anaesthesia. As a second-year student nurse, the role is to assist in providing comprehensive nursing care and support for John throughout his perioperative period, including the pre-operative, intraoperative, and postoperative phases.

Question One 

National Health Priority Area and Pre-operative Nursing Assessments

The National Health Priority Area (NHPA) most relevant to John’s condition is obesity, which is recognised in Australia as a major contributor to chronic disease and increased perioperative risk. John’s BMI of 38 places him in the obesity class II category, significantly influencing his acute health status during an emergency surgical admission. Obesity increases the likelihood of postoperative respiratory compromise, cardiovascular instability, delayed wound healing, thromboembolic events, and challenges with airway management, all of which require proactive pre-operative planning.

The NHPA of obesity influences pre-operative care by emphasising risk identification, optimisation of respiratory status, and preparation for safe anaesthetic management. For John, whose history includes obstructive sleep apnoea (OSA) managed with CPAP, the risk of perioperative hypoventilation, difficult intubation, and postoperative respiratory depression is amplified. Therefore, thorough pre-operative assessment ensures safe transition into the intraoperative phase and supports complication prevention.

Two key pre-operative nursing assessments are essential for obesity-related risk management:

1. Comprehensive Respiratory Assessment
   Obesity combined with OSA increases the risk of airway obstruction, hypoxia, and postoperative atelectasis. A respiratory assessment includes oxygen saturation monitoring, auscultation, assessment of CPAP use, and evaluating the patient’s baseline respiratory pattern. This information guides oxygen therapy planning, airway equipment preparation, and postoperative respiratory support needs.

2. Cardiovascular and Thromboembolic Risk Assessment
   Due to increased intrathoracic pressure and strain related to obesity, the nurse must assess blood pressure, heart rate, peripheral circulation, and venous thromboembolism (VTE) risk. This directs early planning for compression devices, anticoagulation requirements, and intraoperative haemodynamic management.

These assessments ensure patient-centred pre-operative optimisation and reduce avoidable postoperative complications.

Question Two 

Intraoperative Nursing Interventions to Minimise Obesity-related Risks

During surgery, individuals with obesity experience increased risks including impaired ventilation, difficult airway management, reduced tissue perfusion, and higher susceptibility to pressure injuries. Two essential nursing interventions in the intraoperative phase help minimise these risks.

1. Optimising Patient Positioning for Safe Airway and Respiratory Function
   A key intervention is ensuring appropriate positioning, such as ramped or reverse Trendelenburg positioning during induction of anaesthesia. This approach aligns the external auditory meatus with the sternal notch, improving glottic visualisation and facilitating a safer intubation process. Intraoperatively, this position improves diaphragmatic excursion, enhances ventilation-perfusion matching, and reduces airway obstruction. The rationale is that excess adipose tissue in the neck and chest wall compromises respiratory mechanics, and optimised positioning supports adequate oxygenation and ventilation throughout the surgical procedure.

2. Pressure Injury Prevention and Circulatory Support Measures
   The second critical intervention involves using specialised pressure-relieving equipment such as gel pads, foam supports, and meticulous limb protection. Patients with obesity are at heightened risk of pressure injuries due to reduced tissue perfusion, increased skin moisture, and prolonged operative times. Additionally, impaired microcirculation contributes to nerve compression injuries. Implementing padding, repositioning as feasible, and ensuring that no devices exert excessive pressure reduces the likelihood of postoperative skin breakdown. Furthermore, applying intermittent pneumatic compression devices or graduated compression stockings intraoperatively reduces VTE risk by supporting venous return compromised by excess adipose mass.

Both interventions aim to maintain physiological stability and prevent avoidable complications associated with obesity during the intraoperative phase. These strategies optimise safety and support smoother postoperative recovery.

Question Three

Postoperative Nurse-led Interventions to Support Recovery and Prevent Complications

Individuals with obesity who undergo intra-abdominal surgery face heightened postoperative risks, including respiratory compromise, surgical site infection, thromboembolism, impaired mobility, and delayed wound healing. Nurse-led postoperative interventions are essential to supporting John’s recovery and preventing complication progression.

1. Respiratory Support and Early Respiratory Therapy
   A priority intervention is respiratory optimisation through incentive spirometry, CPAP therapy continuation, controlled oxygen delivery, and regular respiratory assessments. Obesity and OSA increase the risk of postoperative hypoventilation, atelectasis, and pneumonia due to reduced lung compliance and the effects of general anaesthesia. Reinforcing airway patency and supporting alveolar recruitment helps maintain adequate gas exchange. The rationale is that early respiratory intervention significantly reduces respiratory complications, enhances ventilation, and prevents oxygen desaturation episodes, especially during early postoperative sedation.

2. Early Mobilisation and VTE Prevention
   The second essential intervention involves mobilising John as soon as clinically safe, supported by physiotherapy collaboration. Obesity increases venous stasis and thromboembolic risk; therefore, combining early mobilisation with VTE prophylaxis (compression devices, stockings, or prescribed anticoagulants) is critical. Mobilisation also enhances respiratory effort, stimulates bowel function, reduces insulin resistance, and prevents muscle deconditioning. The rationale is that active movement reduces the likelihood of deep vein thrombosis and pulmonary embolism while promoting optimal postoperative recovery.

3. Wound Care and Infection Prevention Strategies
   Obesity significantly increases the risk of surgical site infection due to reduced vascularity of adipose tissue, increased moisture, and challenges with maintaining wound integrity. Nurse-led strategies include regular wound assessment, maintaining dressing integrity, monitoring for signs of infection, supporting glycaemic control, and educating the patient on hygiene and wound care. The rationale is that meticulous wound management ensures early detection of complications, supports timely intervention, and promotes effective healing, reducing morbidity.

Together, these interventions provide a comprehensive approach to supporting John’s postoperative recovery and addressing obesity-related risks.
