Neonatal Lung Abscess-Juniper Publishers

Neonatal lung abscess

A baby girl was born at 23+4 weeks by precipitate delivery following spontaneous onset of labour and PROM of 121 hours. Mum had received a course of antenatal steroids. Following two unsuccessful trials of extubation on day 7 and 12, she had a significant cardio respiratory deterioration on day 14. She was started on second line antibiotics. Her CRP went up to 20 and her platelet count dropped to 51. Her chest x ray showed a large bullous emphysematous lesion occupying almost all of her right middle lobe (Figure 1 & 2). She became increasingly difficult to ventilate with worsening acidosis, hypotension and hyperglycemia despite maximizing intensive care support. Following discussion with her parents, her care was redirected to a palliative course. Post mortem examination of lungs revealed widespread collections of neutrophils / abscesses consistent with congenital pneumonia with abscess (seen as cavitating lesion on imaging). Her blood cultures did not reveal any growth.

Neonatal lung abscess is very rare [1] and is often of multibacterial etiology [2,3]. Predisposing factors include prematurity, assisted ventilation, congenital lung anomaly and aspiration. Given the range of potential pathogens, direct culture by percutaneous needle aspiration under either ultrasound [4] or CT guidance [2] is recommended to direct early appropriate intravenous medical therapy and hasten recovery, prevent further complications and obviate the need for surgery [4].

Supraorbital/Supratrochlear Nerve blocks: Clinical Significance of the Superior and Anterior Approaches-Juniper Publishers

Image
Juniper Publishers - Journal of Anesthesia Introduction Hair restoration is one of the commonest cosmetic surgery procedure in men [ 1 ]. The procedure is performed under local anaesthesia. Many of the patients are anxious about the degree of pain to be expected during and after the surgery. The pain of the local anaesthetic agent is dependent on various factors like needle gauge, composition, temperature, pH, speed of injection, anatomical structure/area etc. Various maneuvers are used to decrease the pain during the administration of local anaesthesia like vibration anaesthesia Cryotherapy etc [ 2 - 4 ]. With the introduction of newer drugs for local anaesthesia, the safety is increased. Peripheral nerve blocks constitute a major tool in the armamentarium in the office-based cosmetic surgery procedures. Supraorbital (SO) and supratrochlear (ST) nerve are the terminal branches of the frontal nerve [ 5 ]. These nerves supply mainly the skin of the forehead. These n...

Tourniquet Pain after Ultrasound-Guided Axillary Blockade-Juniper Publishers

Image
Juniper Publishers - Journal of Anesthesia Abstract Objective: To analyse tourniquet pain after ultrasound guided axillary block (AXB) as the sole anesthetic technique with no injection of local anaesthetic into the subcutaneous tissue of the posterior half of the axilla to prevent tourniquet pain. Material/patients and methods: 84 patients older than 18 years ASA I-IV undergoing surgery at hand, wrist, forearm and elbow under ultrasound guided AXB requiring upper arm tourniquet, we studied prospectively. Exclusion criteria included refusal to participate, communication problems, pre-existing neuropathy, coagulopathy or allergy to local anaesthetics. Tourniquet pain was assessed according to visual analogue scale (VAS) every 15 minutes. We also analysed differences in tourniquet pain between sedated and non-sedated patients. Main results: VAS was 0 during ischemia in 83 patients. One patient reported tourniquet pain. This was mild (VAS = 3) and reported duri...

Heerfordt's Syndrome: A New Atypical Clinical Presentation-Juniper Publishers

Image
Juniper Publishers - Journal of Anesthesia Abstract Heerfordt’s syndrome is an unusual clinical manifestation (less than 5%) of sarcoidosis, characterized by parotitis, uveitis, and peripheral facial palsy, febrile syndrome is usually associated. Oral corticosteroid is the treatment of choice. We report a case of a patient in which the syndrome of Heerfordt was retained. Keywords: Heerfordt’s syndrome, parotitis, uveitis, sarcoidosis, facial palsy. Introduction The sarcoidosis is a systemic granulomatosis of unknown cause, characterized by its clinical polymorphism and a wide variety of its modes of presentation. The combination of fever, uveitis, parotitis and peripheral facial paralysis defines Heerfordt’s syndrome which presents an unusual manifestation of this disease. We report a case of a patient in which the syndrome of Heerfordt was found. Case Report A 49 year-old female followed i...
