Small bowel obstruction management, updated ACLS rhythm decisions, pacemaker troubleshooting and red flags in the limping child
In suspected small bowel obstruction, examine the groins early; a hernia-related obstruction carries high strangulation risk and should not be managed conservatively.
Small bowel obstruction provides the main acute surgical thread. Crampy abdominal pain, distension, vomiting, obstipation, previous surgery and a CT transition point should prompt early examination of the abdomen and groins, IV fluids, electrolyte correction, nil by mouth status and effective large-bore nasogastric decompression. Stable adhesive obstruction may be suitable for a structured non-operative trial and water-soluble contrast challenge after decompression, but fever, tachycardia, raised lactate, peritonism, free air, pneumatosis, portal venous gas, closed-loop obstruction or hernia should move the discussion towards urgent operative decision-making.
Cardiorespiratory material spans ACLS updates and pacing. Unstable atrial fibrillation or flutter requires synchronised cardioversion with the intended energy stated clearly before shock delivery. Stable ventricular tachycardia still needs continuous monitoring, early escalation and antiarrhythmic treatment with amiodarone or procainamide. Refractory ventricular fibrillation should not become repetitive standard shocks alone; pad vector change or double sequential defibrillation may be considered when equipment and trained staff are available. In pacing, symptom frequency should determine ambulatory monitoring length, and a symptomatic sinus pause provides clinically meaningful rhythm-symptom correlation. Acute low lead impedance after generator change points towards insulation breach rather than lead fracture.
The paediatric episode adds a common diagnostic challenge: limp or refusal to weight bear. Age narrows the differential, but fracture, infection, inflammatory disease, malignancy and maltreatment remain possible at any age. Hip disease may present as knee pain, so the joint above and below the painful area must be examined. Fever, night pain, unexplained bruising, systemic symptoms, inability to weight bear and a palpable mass are red flags that should prevent premature reassurance. The remaining episodes support safer consultations, with PACES-style communication skills and more deliberate screening for perimenopause, bipolar features and sleep apnoea when psychiatric or ADHD-like symptoms change.
General surgery, gastroenterology and emergency clinicians get a practical small bowel obstruction framework. It links crampy abdominal pain, distension, vomiting, obstipation, previous surgery and CT transition point with IV fluids, electrolyte correction, nil by mouth status, large-bore nasogastric decompression, water-soluble contrast challenge and operative escalation when strangulation risk appears.
Cardiology and acute medicine teams get a structured approach to recurrent presyncope, sinus node disease and pacemaker troubleshooting. Symptom frequency guides ambulatory ECG choice, while symptomatic sinus pause, DDDR pacing, pacemaker syndrome, lead impedance, insulation breach and loss of capture shape pacing decisions and device review.
Medical education and human-factors readers get a PACES communication-skills update. The episode focuses on open questions, patient-centred agenda setting, clear signposting, plain-language explanation, empathy, structured closure and concise examiner presentations without over-rehearsed or insincere stock phrases.
Psychiatry, obstetrics and gynaecology, respiratory and primary-care clinicians get a midlife mental-health prescribing update. Perimenopausal depression, bipolar caution, vasomotor symptoms, HRT referral, ADHD symptoms, sleep apnoea screening, atomoxetine, gabapentin, melatonin and adjuncts such as clonidine, L-methylfolate and saffron are kept in view.
Emergency, cardiology and critical-care clinicians get a resuscitation update covering unstable atrial fibrillation, stable ventricular tachycardia, refractory ventricular fibrillation and post-arrest care. Practical points include synchronised shock energy, amiodarone or procainamide, vector-change or double sequential defibrillation, vascular access and post-ROSC targets.
Paediatric, emergency and orthopaedic clinicians get an age-structured review of limp, refusal to weight bear and antalgic gait. Toddler’s fracture, transient synovitis, Perthes disease, slipped upper femoral epiphysis, Osgood-Schlatter disease, infection, malignancy and maltreatment are linked to red-flag screening and joint-above-joint-below examination.
For suspected small bowel obstruction, document abdominal scars, distension, tenderness, peritonism and groin examination before relying on imaging alone. Start fluids, electrolyte correction, nil by mouth status and large-bore nasogastric decompression early. Escalate promptly when clinical or CT features suggest strangulation, closed-loop obstruction, perforation or obstructing hernia.
A patient with previous abdominal surgery has vomiting, abdominal distension and obstipation. CT confirms small bowel obstruction without peritonism, fever, raised lactate, closed-loop obstruction or hernia. What initial management is appropriate?
Start IV fluids, correct electrolytes, keep the patient nil by mouth and insert an effective large-bore nasogastric tube for decompression. Stable adhesive obstruction can then be considered for a structured non-operative trial and water-soluble contrast challenge after adequate decompression.
During updated ACLS care, what is the recommended first synchronised shock energy for unstable atrial fibrillation or flutter?
Use 200 J as the first synchronised shock for unstable atrial fibrillation or flutter. Confirm synchronised mode and state the intended energy aloud before shock delivery.
A child has knee pain and a limp, but no obvious knee abnormality. What important diagnostic principle should guide examination?
Hip pathology can refer pain to the thigh or knee, including Perthes disease and slipped upper femoral epiphysis. Examine the joint above and below the painful area, and screen for red flags such as fever, night pain, systemic symptoms, bruising or inability to weight bear.
