Clinical General Surgery & Bedside Planning Tools
In perioperative and general surgery, precision planning reduces post-operative complications and optimizes recovery times. Bedside calculators help surgical teams, registrars, and intensive care units standardise pre-operative risk assessments, audit fluids and blood loss levels, and optimize caloric nutrition targets to support healing.
Primary Surgical Planning Tools
Our surgeons' portal contains calculations standard across pre-op, intra-op, and post-op care:
- Pre-Operative Risk Staging: Integrates the Caprini DVT Risk model to guide pharmacologic venous thromboembolism (VTE) prophylaxis.
- Intraoperative Fluid & Hemorrhage: Calculates Allowable Blood Loss (ABL), estimated surgical blood loss based on hematocrit shifts, and perioperative fluid demands.
- Burn Resuscitation: Combines TBSA burn classifications (Rule of Nines) with the Parkland formula.
- Post-Operative Caloric Goals: Estimates resting energy expenditure using Mifflin-St Jeor equations to scale post-surgical clinical nutrition.
- Surgical Prophylaxis Dosing: Identifies standard antibiotic dosing windows and therapeutic ranges.
BEDSIDE FAQs
The Caprini score is a comprehensive assessment evaluating over 30 VTE risk factors (e.g., surgical complexity, age, mobility, genetic thrombophilias). A high score (≥ 5, classified as High Risk) mandates mechanical prophylaxis (sequential compression devices) combined with pharmacological prophylaxis (low-molecular-weight heparin like enoxaparin) post-operatively, unless contraindicated by bleeding risk.
Hypermetabolic post-operative states dramatically increase protein and caloric requirements. Inadequate nutritional support can lead to poor wound healing, suture line failure (dehiscence), muscle wasting, and increased infection rates. Using Mifflin-St Jeor equations to target accurate resting metabolic calorie baselines ensures appropriate enteral or parenteral nutrition delivery.
