Digital Perioperative Surveillance with Multiparameter Vital Signs Monitoring System in Gastric Cancer Surgery

1. Background: The Need for Intelligent Perioperative Monitoring

Patients undergoing major abdominal surgery often experience significant physiological stress.

For gastric cancer patients, postoperative management can be challenging due to:

• Surgical trauma

• Cardiovascular stress

• Blood glucose fluctuations

• Risk of infection

• Reduced mobility

• Respiratory complications

Traditional monitoring methods usually rely on periodic measurements, which may miss temporary physiological changes occurring between clinical assessments.

Digital multiparameter monitoring technology provides a new approach by enabling:

• Continuous physiological data collection

• Real-time abnormal event alerts

• Dynamic patient status assessment

• More personalized perioperative management

2. Clinical Case: Gastric Cancer Patient Receiving Full-Cycle Digital Monitoring

Researchers from:

The First Clinical Medical College, Nanjing University of Chinese Medicine and Affiliated Hospital of Nanjing University of Chinese Medicine

evaluated a digital monitoring system in a gastric cancer patient complicated with diabetes mellitus.

The patient received continuous monitoring throughout the entire surgical pathway:

Preoperative evaluation → Surgery → Postoperative recovery → Hospital discharge

3. Components of the Digital Monitoring System

The multiparameter monitoring platform combined multiple wearable and intelligent medical devices, including:

Wireless Ambulatory ECG Patch

Provided continuous monitoring of:

• Electrocardiogram changes

• Heart rate trends

• Heart rate variability (HRV)

The HRV analysis helped evaluate physiological stress responses during the perioperative period.

Continuous Glucose Monitoring Sensor

Enabled:

• Real-time blood glucose tracking

• Detection of glucose fluctuations

• Better diabetes management during recovery

This was especially valuable for patients with metabolic disorders undergoing major surgery.

Pulse Oximeter

Continuous oxygen saturation monitoring helped identify:

• Early oxygen desaturation

• Respiratory abnormalities

• Potential postoperative complications

Wireless Digital Thermometer

Provided continuous body temperature monitoring to support early detection of:

• Fever

• Infection-related changes

• Inflammatory responses

Smart Wristband and Bioelectrical Impedance Analyzer

Collected additional physiological information, including:

• Physical activity level

• Recovery progress

• Body composition changes

These parameters supported evaluation of postoperative rehabilitation.

4. Four-Level Digital Data Management Architecture

The collected physiological information was integrated through a multi-layer digital healthcare platform:

Level 1: Nurse Mobile Interface

Enabled medical staff to receive alerts and review patient information quickly.

Level 2: Bedside Patient Terminal

Allowed direct visualization of monitoring data during hospitalization.

Level 3: Centralized Ward Monitoring Display

Supported continuous observation of multiple patients.

Level 4: Hospital Information Management System

Connected monitoring data with hospital digital infrastructure.

This architecture improved information flow between patients, nurses, doctors, and hospital management systems.

5. Clinical Results: Early Detection and Improved Recovery Management

The study demonstrated several important clinical benefits.

Early Identification of Postoperative Abnormalities

The monitoring system successfully detected:

• Decreased oxygen saturation

• Blood glucose fluctuations

These alerts provided clinicians with timely information for intervention.

Visualization of Surgical Stress Response

By combining:

• Heart rate variability analysis

• Continuous glucose monitoring data

the system provided a clearer picture of the patient's physiological stress level during recovery.

Supporting Enhanced Recovery After Surgery (ERAS)

Continuous monitoring encouraged early postoperative mobilization.

The patient showed:

• Good compliance with rehabilitation activities

• Improved recovery management

Patient satisfaction with monitoring management reached:

4 points out of 5 on the Likert satisfaction scale

6. Clinical Value of Digital Multiparameter Monitoring Systems

This case demonstrates that digital monitoring technology can provide significant advantages in modern surgical care.

✔ Continuous Full-Cycle Surveillance

Monitoring begins before surgery and continues until discharge, creating a complete patient health profile.

✔ Earlier Risk Detection

Real-time alerts help clinicians identify potential complications before they become severe.

✔ Data-Driven Clinical Decisions

Multiple physiological parameters provide comprehensive information beyond traditional vital signs measurement.

✔ Supporting Smart Hospital Development

Integration with hospital information systems helps build more efficient and intelligent healthcare workflows.

Conclusion

The application of a multiparameter vital signs monitoring system represents an important advancement in perioperative digital healthcare.

For gastric cancer patients undergoing surgery, continuous monitoring of ECG, blood glucose, oxygen saturation, temperature, activity, and body composition provides clinicians with comprehensive physiological insights.

By combining wearable medical technology with intelligent data analysis, digital monitoring systems can improve early warning capabilities, support enhanced recovery pathways, and contribute to safer and more personalized surgical care.
