The night before a scheduled cesarean is mostly about following your hospital’s fasting instructions, showering with the right soap, and getting yourself as rested and organized as possible. Most of what you need to do takes less than an hour, but the timing matters, especially when it comes to eating and drinking.
When to Stop Eating and Drinking
The standard guideline is to stop eating solid food 6 to 8 hours before your surgery and stop drinking clear liquids 2 hours before. These timeframes come from the American Society of Anesthesiologists and are designed to keep your stomach empty during anesthesia. When your stomach contains food or liquid during surgery, there’s a small but serious risk of vomiting and inhaling that material into your lungs, which can cause severe respiratory distress.
For most people with a morning surgery time, this means eating a normal dinner the night before and then nothing else solid after that. Clear liquids like water, apple juice, black coffee, or tea without milk are fine up until two hours before your scheduled time. Your hospital will give you a specific cutoff, so follow their instructions if they differ from this general rule.
Some hospitals now encourage drinking a carbohydrate-rich clear liquid (essentially a sugary drink mixed in water) about two hours before surgery. This falls under newer enhanced recovery protocols. Research shows that women who had a carbohydrate drink before their cesarean reported significantly less hunger, thirst, and anxiety, and scored higher on post-surgery recovery assessments covering pain, nausea, and overall comfort. If your hospital doesn’t mention this, ask whether it’s an option. It’s considered safe for women without diabetes having an uncomplicated scheduled cesarean, with studies confirming that up to 400 ml of clear liquid empties from the stomach safely within that two-hour window.
Shower With Antiseptic Soap
Your hospital will likely ask you to shower with a chlorhexidine wash (Hibiclens is the most common brand) the night before surgery and again the morning of. This antiseptic skin cleanser reduces bacteria at the surgical site and lowers your risk of infection. The process is straightforward but has a few specific steps that matter:
- Wash normally first. Use your regular shampoo and soap on your hair, face, and body, then rinse completely.
- Apply the chlorhexidine from neck to feet. Use your hand or a washcloth. Avoid your face and genital area.
- Let it sit for two full minutes. This contact time is what actually kills bacteria, so don’t rinse it off early.
- Rinse, then skip all other products. After drying off with a clean towel, don’t apply lotion, deodorant, powder, perfume, or makeup. These can interfere with monitoring equipment or reintroduce bacteria to your skin.
Dress in clean clothes and sleep on clean sheets afterward.
Don’t Shave the Surgical Area
If you’re thinking about shaving your bikini line before surgery, don’t. Shaving with a razor roughly doubles the risk of a surgical site infection compared to leaving hair alone, based on a Cochrane review of seven studies. Razor blades create tiny nicks in the skin that become entry points for bacteria. If hair needs to be removed, your surgical team will use electric clippers at the hospital, which cause significantly fewer infections than razors. The same goes for depilatory creams, which are also safer than shaving if you feel strongly about it.
Remove Nail Polish and Acrylics
During surgery, a small clip on your finger continuously monitors your blood oxygen levels. Nail polish and gel manicures interfere with the light sensors in that device. Dark colors like black and blue can lower readings by 3 to 6 percentage points, which could mask a real drop in oxygen. Even gel polishes in lighter shades can skew readings in the opposite direction, making your levels look better than they are. Remove polish from at least one or two fingernails the night before. If you have gel or acrylic nails, you may need acetone or a nail salon visit, so plan ahead.
Review Your Medications
If you haven’t already discussed your medication list with your OB or anesthesiologist, the night before is your last chance to confirm what to take and what to skip. Blood thinners and anti-inflammatory medications like ibuprofen are commonly paused before surgery, sometimes days in advance. Some medications are fine to take the morning of with a small sip of water. If you’re unsure about any supplement or prescription, call your provider’s office or the labor and delivery unit rather than guessing.
Pack Your Hospital Bag
You’ll typically stay in the hospital for two to three days after a cesarean, so pack accordingly. A few items are especially useful for c-section recovery specifically: a robe or button-front shirt makes nursing and skin-to-skin contact easier when you can’t easily pull things over your head. High-waisted maternity underwear sits above the incision line rather than rubbing against it. Slip-on slippers help because bending down to tie shoes will be difficult for the first couple of days.
Beyond that, bring your toiletries, a phone charger, loose and comfortable going-home clothes (think the size you were at about six months pregnant), a nursing bra without underwire, cotton socks, snacks for after surgery, and anything for your baby that the hospital doesn’t provide like a going-home outfit and a car seat installed in your vehicle. Check your hospital’s specific list, since some provide more than others.
Plan Your Morning Timeline
Most hospitals ask you to arrive about two hours before your scheduled surgery time. That pre-op window covers confirming your medical history, starting an IV for fluids and antibiotics, and meeting your anesthesiologist. Work backward from your arrival time the night before: figure out when you need to wake up, when to do your second antiseptic shower, and when your clear liquid cutoff hits. If you have other children, confirm your childcare plan is locked in.
Managing Pre-Surgery Anxiety
It’s completely normal to feel anxious the night before, even if this isn’t your first cesarean. A few approaches have evidence behind them. Listening to music before surgery has been shown in several studies to reduce anxiety. Slow breathing exercises, progressive muscle relaxation, and meditation also help, and you don’t need prior experience to try them. Free guided recordings are widely available on apps and streaming platforms.
Some people manage anxiety better by gathering information in advance, while others do better by distracting themselves with a book or show. Neither approach is wrong. If your anxiety is severe enough that you can’t sleep, your hospital may be able to call in a mild sedative, though this is more common for people already admitted the night before. For most scheduled cesareans where you arrive the morning of, the practical focus of getting everything ready tends to keep your mind occupied enough to get through the evening.
