5:15 PMAlarm. The apartment is quiet. June is out, probably at the gym before her Sunday day shift. I eat leftover pad thai standing in the kitchen and drink a large coffee, the first of what will be many. Getting ready for a 12-hour overnight is its own ritual: scrubs, sneakers with insoles, hair tied back, stethoscope in my bag, granola bars in my pocket. I've been doing the Saturday overnight for eight months. My body still hasn't fully adjusted to sleeping until 2 PM on Sundays. I'm not sure it ever will.
5:50 PMDriving to the hospital. It's a 24-hour facility in West Philadelphia, one of the biggest emergency animal hospitals in the region. On a Saturday night we run two doctors, four technicians, and a receptionist from 6 PM to 6 AM. My senior tech tonight is Roz, who has been an ER tech for 9 years and who teaches me more on any given shift than vet school managed in four years. Roz has the kind of calm that only comes from having seen everything twice. I trust her instincts more than I trust my own, and I'm not embarrassed to say that because it keeps patients alive.
6:10 PMShift handoff from the day team. Three patients in the treatment area from earlier: a post-surgical cat recovering from a urinary obstruction unblock, a dog on IV fluids for pancreatitis, and a parrot with a wing fracture that the exotics specialist will see Monday. The day doctor tells me it's been quiet. That word is forbidden in this building. Roz shoots her a look. The day doctor grins and walks out. Tevin, our overnight receptionist, is already at the front desk. He's 24 and unflappable. At 2 AM when a distraught owner is screaming and crying simultaneously, Tevin's voice is the same steady register it was at 6 PM. That skill is worth more than any credential on my wall.
7:35 PMFirst emergency of the night. A 5-year-old mixed breed named Pepper, hit by a car 30 minutes ago. The owners are a young couple, both crying. Pepper is on a stretcher, conscious but not moving her hind legs. I do my primary survey: airway clear, breathing labored but stable, heart rate 160, gums pale pink. She's in shock. Roz has an IV catheter in her cephalic vein within 90 seconds. We start a crystalloid bolus. I do a focused abdominal ultrasound looking for free fluid, which would indicate internal bleeding. There's a small amount in the abdomen. Not enough to panic. Enough to watch. I take radiographs. Pelvic fracture, left ilium and ischium. No spinal displacement. The fact that she still has deep pain sensation in her hind feet means her spinal cord is likely intact. I exhale for the first time in ten minutes.
8:15 PMI talk to Pepper's owners. Pelvic fractures in dogs often heal with strict rest and pain management unless they're severely displaced. Pepper's fracture will need a surgical consult in the morning, but she's stable and her neurological signs are encouraging. The owners ask if she'll walk again. I say the odds are very good but I want the surgeon to confirm. They ask if they can sit with her. I say yes. They sit on the floor next to Pepper's kennel and don't move for four hours. This is the thing about emergency medicine that no one tells you in school: half the job is managing the animal, and the other half is managing the grief and fear of the people who love the animal. Those two halves are equally demanding.
9:05 PMSecond emergency. A 6-year-old male cat named Ringo, blocked. Urinary obstruction. He's been straining in the litter box all day and his owner finally brought him in when he started vomiting. I palpate his bladder and it's hard as a baseball and the size of a grapefruit. This is life-threatening if we don't relieve it. Potassium builds up when a cat can't urinate, and elevated potassium stops the heart. I run an I-STAT: potassium is 7.8. Normal is under 5.5. We need to move. Roz already has the unblocking tray set up before I finish looking at the bloodwork. I sedate Ringo, pass a urinary catheter to relieve the obstruction, and we start IV fluids to flush his system. The urine that drains is bloody and thick with crystals. His bladder deflates. His heart rate, which was dangerously slow from the potassium, starts to normalize within 20 minutes. Ringo will spend the night with us on fluids and a catheter. He'll probably be OK. "Probably" is the most honest word in emergency medicine.
10:15 PMTwo more cases back to back. A dog with a lacerated paw pad from stepping on glass. Five sutures, a bandage, and antibiotics. Then a cat with an abscess on her cheek from a fight. I lance it, flush it, and send her home with pain meds. Neither case is dramatic. Both require focus, both require local anesthesia and wound care, and both involve owners who are scared because it's Saturday night and they're at the animal ER and everything feels more serious at night. They're not wrong. It does feel more serious at night. The fluorescent lights make everything look a little more clinical, a little more urgent. Shadows are sharper. The beeping of monitors is louder when the rest of the world is quiet.
11:10 PMChocolate case. A 70-pound chocolate Lab named Bruno ate approximately 24 ounces of dark chocolate two hours ago. His owner found the empty bag and the wrapper. Dark chocolate has the highest theobromine concentration of any chocolate type, and 24 ounces in a 70-pound dog is a potentially lethal dose. Theobromine is the compound in chocolate that's toxic to dogs. It causes vomiting, diarrhea, hyperactivity, seizures, and cardiac arrhythmias at high doses. I induce vomiting with apomorphine. Bruno vomits enthusiastically. A lot of chocolate comes back up, but I can't know how much he's already absorbed. I give activated charcoal to bind whatever's left in his GI tract, start IV fluids, and put him on continuous ECG monitoring. His heart rate is already elevated at 140. We'll be watching Bruno all night.
12:30 AMSeven emergencies so far. I check on all my patients. Pepper is sleeping, her owners finally went home after I promised to call if anything changed. Ringo's potassium is down to 5.9 on recheck. Bruno's heart rate is 130 and holding, no arrhythmias yet. The post-surgical cat from earlier is eating, which is a good sign. I drink my third coffee. Roz asks if I've eaten. I have not. She produces a bag of pretzels from a drawer and puts them on my keyboard. "Eat," she says. It's not a suggestion.
1:45 AMA lull. This is the window between midnight and 3 AM when things either stay quiet or explode. I use it to write medical records for every case so far. Records in the ER are different from GP records. Everything is time-stamped to the minute. Every drug, every dose, every vital sign, every decision. If a case goes to litigation, which happens more often in emergency medicine than you'd think, the medical record is the only thing that matters. I write thorough records not because I enjoy it but because 2 AM Gemma owes it to future Gemma who might be explaining these decisions to a board or a lawyer.
2:40 AMBruno starts tremoring. Mild muscle tremors, which is a theobromine effect. His heart rate bumped to 155. No arrhythmia on the ECG but we're getting closer to the clinical effects I was worried about. I give a dose of methocarbamol for the tremors and adjust his fluid rate. Roz and I sit with him for 20 minutes until the tremors subside. His heart rate comes back to 135. He's going to be a long night. I'm running the theobromine dose calculation in my head for the third time. At his body weight and the estimated amount ingested, he's in the moderate to severe toxicity range. The next six hours will tell us which side of that range he falls on.
3:15 AMThe ER is quiet except for the monitors. The fluorescent lights hum at a frequency you only hear at 3 AM, when every other sound in the building has stopped. I do a round. Pepper is stable. Ringo is urinating through his catheter, which is exactly what we want. Bruno is sleeping, heart rate 128, down from the spike. The other patients are settled. Tevin is reading a paperback at the front desk. Roz is restocking the crash cart. I sit in the treatment area and feel the exhaustion hit, the specific kind that arrives at 3 AM and sits on your chest like a weight. Not sleepy. Heavy. Your body knows what time it is even when your brain is still working. I eat a granola bar and keep going.
4:30 AMThe phone at the front desk rings and Tevin's voice shifts, which means it's bad. A 4-month-old puppy is seizing at home. The owners are 15 minutes away. Roz and I prep: diazepam drawn up, IV catheter supplies ready, oxygen, fluid pump primed. When they arrive, the puppy, a French Bulldog named Olive, is actively seizing in the owner's arms. Roz takes her. I give diazepam IV through the catheter Roz places in under a minute. The seizure stops. Olive is post-ictal, disoriented, paddling her legs. Her temperature is 105.2 from the prolonged muscle activity. We start cooling measures. I run bloodwork. Glucose is low at 42. I give a dextrose bolus. In a puppy this age, the differential for seizures includes hypoglycemia, a liver shunt, toxin ingestion, infection, or congenital epilepsy. I need more data. But right now, at 4:45 AM, I just need her to stop seizing and start stabilizing. She does.
5:20 AMOlive is stable, temperature down to 102.8, no more seizures. Her glucose is holding after the dextrose. I talk to her owners, a young woman and her mother, both in pajamas, both terrified. I explain what happened and what we're testing for. I tell them we'll need a bile acids test and possibly an MRI to rule out a liver shunt. They nod. The mother asks "Is she going to be OK?" I say "She's stable right now, and that's the most important thing." I say that because it's true, and because at 5:20 AM, after 11 emergencies and 12 hours of fluorescent light and monitor beeps, the most honest thing I can offer is what I know right now, not what I hope.
5:55 AMThe day team starts arriving. I hand off: Pepper, stable, surgical consult in the morning. Ringo, catheter patent, potassium normalized, recheck in four hours. Bruno, tremors resolved, heart rate stable, continue monitoring and fluids for another 12 hours. Olive, post-seizure, glucose-dependent, needs bile acids and further workup. Four other cases discharged during the night. Eleven emergencies total. I pull off my stethoscope and it leaves a red mark on my neck that will take an hour to fade.
6:15 AMWalking to my car. The sun is coming up over West Philadelphia and the sky is that pale orange-pink that only exists at 6 AM and that I only see on Sunday mornings after a Saturday overnight. The air is cold and clean and doesn't smell like antiseptic. I sit in my car for two minutes before starting it. Not because I'm too tired to drive. Because the silence is the first I've heard in 12 hours and I want to hold it for a second.
7:00 AMHome. June is awake, already in her scrubs, making coffee. She hands me a mug without asking. She looks at my face and says "How many?" I say "Eleven." She nods. She doesn't ask what kind or how bad or if I'm OK, because she already knows all of those answers from the number and from the way I'm standing. She's heading to the ICU in an hour. She'll see human versions of everything I saw tonight. We drink coffee in the kitchen while the sun fills the apartment. I'll shower and sleep until 2 PM. I'll wake up and check my phone for updates on Olive and Bruno. I'll eat something and exist as a person for a few hours. And next Saturday I'll do it again, because this is the job, and the job doesn't stop at night, and someone has to be the one who's there when the phone rings at 4:30 AM about a seizing puppy. Tonight it was me. Next week it'll be me again. That's not a complaint. It's just the math.
