  • Comparative study between sugammadex and neostigmine in Neurosurgical Anesthesia in pediatric patients
    Wolters Kluwer Medknow Publications, 2015
    Co-Authors: Ayman A Ghoneim, Mohammed El A Beltagy
    Abstract:

    Background: Postoperative recurarization remains a risk following the use of the conventional neuromuscular blocking agents. In addition, none of the commonly used reversal agents, such as neostigmine or edrophonium are capable of reliably reversing profound blockade. The present comparative and randomized study investigated the use of sugammadex for reversing profound neuromuscular blockade (NMB) in pediatric Neurosurgical patients undergone posterior fossa tumor excision. Patients and Methods: Forty pediatric patients undergoing elective craniotomy for posterior fossa tumor excision were randomly divided into either of neostigmine or sugammadex group in which muscle relaxant was reversed at the end of Anesthesia either with neostigmine 0.04 mg/kg added to atropine 0.02 mg/kg or sugammadex 4 mg/kg alone, respectively. The primary endpoint was the time from the administration of sugammadex or neostigmine to recovery of the train of four (TOF) ratio to 90% after rocuronium-induced neuromuscular block. Unpaired t-test was used to compare continuous variables between groups. Meanwhile, repeated ANOVA was used to detect intragroup differences. Results: Patients in sugammadex group attained a TOF ratio 90% in statistically shorter time (1.4 ± 1.2 min) than those in neostigmine group (25.16 ± 6.49 min) for reversal of the rocuronium. Mean arterial pressure and heart rate were significantly higher in neostigmine group at 2, 5 and 10 min after administration of the reversal agents and returned nonsignificantly different after that. With no recurarization in any patient throughout the study period. Conclusion: Sugammadex rapidly and effectively reverses rocuronium-induced NMB in pediatric patients undergoing neurosurgery when administered at reappearance of T2 of TOF at dose 4 mg/kg

  • NORMOBARIC HYPEROXIA IN NEUROAnesthesia
    Academy of Medical Sciences of Croatia, 2018
    Co-Authors: Martina MikliĆ BubliĆ, Marijana Matas, Ante SekuliĆ
    Abstract:

    Normobarična hiperoksija se sporadično opisuje u literaturi o neurokirurškoj anesteziji. Mišljenja o toj temi su različita. Dugi niz godina hiperoksiju se povezivalo s mogućim štetnim učincima slobodnih kisikovih radikala, koji se tijekom hiperoksije stvaraju u količini većoj nego što je kapacitet antioksidansa, uzrokujući hiperoksičnu akutnu ozljedu pluća. Nedavna istraživanja pokazuju da normobarična hiperoksija može biti korisna u liječenju traumatske ozljede mozga. Glavni ciljevi u neuroanesteziji su održavanje intrakranijskog tlaka, cerebralnog perfuzijskog tlaka te sprječavanje sekundarne ozljede mozga. Hiperoksija poboljšava oksigenaciju moždanog tkiva i aerobni metabolizam u mozgu zbog čega može biti neuroprotektivna. Dodatna korist hiperoksije je u liječenju poslijeoperacijskog pneumocefalusa, u smanjenju poslijeoperacijske mučnine i povraćanja, učestalosti infekcija kirurških rana te njihovom bržem cijeljenju, što omogućuje bolju kvalitetu oporavka bolesnika. Uzevši u obzir moguće dobrobiti normobarične hiperoksije te njenih neželjenih učinaka potrebna su daljnja istraživanja kako bi se jasno izdvojile skupine bolesnika u kojih hiperoksija može poboljšati ishod liječenja.Normobaric hyperoxia is occasionally mentioned in the literature concerning Neurosurgical Anesthesia. Opinions vary on this subject. Hyperoxia was long related to the potentially harmful influence of reactive oxygen species that are produced during hyperoxia in the amounts greater than the antioxidant capacity, thus causing hyperoxic acute lung injury. Recent research shows that hyperoxia may be benefi cial in treating traumatic brain injury. The main goals in neuroAnesthesia are maintaining intracranial pressure and cerebral perfusion pressure while preventing secondary brain injury. Hyperoxia enhances brain tissue oxygenation and brain aerobic metabolism, thus being neuroprotective. Additional benefi t of hyperoxia may be found in the treatment of postoperative pneumocephalus by diminishing postoperative nausea and vomiting, and reducing the incidence of surgical site infections and facilitating their healing, thus providing better patient recovery. Considering the potential benefi ts of normobaric hyperoxia and its possible detrimental effect, additional investigation is needed to clearly defi ne the patient category where hyperoxia may have positive effect on patient outcome
