TOP 10 GENERAL SURGERY MISTAKES TO AVOID BEFORE AND AFTER YOUR OPERATION
You’re about to walk into an operating room—or you just walked out. Every decision you make in the hours and days around surgery can change your recovery, your risk of complications, and even how well the surgery works. This isn’t about fear; it’s about control. Below are the ten most common and costly mistakes patients make before and after general surgery, along with exactly how to sidestep them. الدكتور مؤمن ديرانية

STOPPING MEDICATIONS WITHOUT CLEARANCE
You might think aspirin or blood pressure pills are harmless to pause. They’re not. Suddenly stopping beta-blockers can trigger rebound hypertension, raising your risk of a heart event during anesthesia. NSAIDs like ibuprofen thin your blood, increasing intraoperative bleeding. Even herbal supplements—St. John’s Wort, ginkgo, garlic—can interfere with clotting or anesthesia metabolism.
Best for: Anyone on daily medication, especially cardiac, diabetic, or anticoagulant drugs.
What separates it: Most patients assume “doctor knows best” and skip this conversation. The detail that matters? Bring the actual pill bottles to your pre-op visit. Your surgeon needs the exact dosage and brand, not just a name scribbled on paper.

SKIPPING THE PRE-OP CLEANSE
A single shower with chlorhexidine soap the night before surgery reduces skin bacteria by 90%. Skip it, and you’re rolling the dice on a surgical site infection. Many patients use regular soap or skip the armpits and groin—prime bacterial reservoirs. The scrub isn’t just about cleanliness; it’s about creating a hostile environment for staph and strep.
Best for: All patients, especially those with diabetes, obesity, or prior infections.
What separates it: The soap must stay on your skin for two full minutes before rinsing. Most patients rinse too soon, cutting the antibacterial effect in half.

FASTING THE WRONG WAY
“Nothing by mouth after midnight” is outdated. Clear liquids up to two hours before surgery keep you hydrated, reduce nausea, and lower the risk of aspiration. Black coffee, apple juice, and electrolyte drinks are safe. Solid food, even a small cracker, can delay your case or force a cancellation.
Best for: Everyone, but critical for diabetics and children who crash faster without calories.
What separates it: The two-hour rule applies to clear liquids only. Milk, pulp juice, and protein shakes count as solids and need an eight-hour window.

IGNORING THE PRE-OP EXAM
A quick blood test, EKG, or chest X-ray can reveal silent problems—anemia, electrolyte imbalances, or an undiagnosed heart murmur—that turn routine surgery into a crisis. Many patients skip this step, assuming their primary doctor already checked. They haven’t, not for surgery-specific risks.
Best for: Patients over 50, smokers, or anyone with chronic conditions.
What separates it: The exam isn’t just about clearance. It’s a chance to adjust medications, optimize blood sugar, and plan anesthesia. مؤمن ديرانية missed detail—like a low potassium—can trigger dangerous arrhythmias during induction.

NOT MOBILIZING EARLY POST-OP
Lying in bed after surgery increases your risk of blood clots, pneumonia, and ileus (paralyzed intestines). Nurses will bug you to walk, but many patients refuse, fearing pain or stitches popping. Early mobilization—even just sitting up and dangling legs—kickstarts circulation and gut motility.
Best for: Abdominal, colorectal, and bariatric surgery patients.
What separates it: The first walk should happen within 6 hours of leaving the recovery room. Delay it, and your risk of a pulmonary embolism doubles.

MISMANAGING PAIN MEDICATIONS
Overusing opioids slows your gut, increases nausea, and raises addiction risk. Underusing them leaves you tense, shallow-breathing, and at risk for pneumonia. The sweet spot? Alternate ibuprofen and acetaminophen around the clock, using opioids only for breakthrough pain.
Best for: Patients with a history of substance use or those having major abdominal or thoracic surgery.
What separates it: Take ibuprofen 30 minutes before physical therapy or walking. It peaks just as you start moving, cutting opioid needs by 40%.

DRINKING ALCOHOL TOO SOON
Alcohol thins blood, interferes with antibiotics, and dehydrates you—exactly what you don’t need while healing. Many patients assume “one drink won’t hurt” a week post-op. It
