ABSTRACT

Abstract Thoracic trauma with rib fractures is a challenging condition due to the severe associated pain. Uncontrolled pain impairs breathing and an adequate pain control is necessary to provide comfort and to avoid further complications. Serratus Anterior Plane block is a procedure safe and easy to accomplish. The authors describe a case of thoracic trauma with rib fractures and respiratory compromise. Pain control was only achieved after performing a Serratus Anterior Plane block. The technique was done as described in the medical literature with placement of a catheter. Pain relief was achieved with a low concentration infusion of local anesthetic.


Resumo O trauma torácico com fraturas de costelas é uma condição desafiadora devido à dor intensa associada. O não controle da dor prejudica a respiração enquanto, o seu controle adequado é necessário para proporcionar conforto e evitar maiores complicações. O bloqueio do plano serrátil anterior é um procedimento seguro e fácil de fazer. Descrevemos um caso de trauma torácico com fraturas de costelas e comprometimento respiratório. O controle da dor só foi obtido após o bloqueio do plano serrátil anterior. A técnica foi aplicada conforme descrito na literatura médica, com a colocação de um cateter. O alívio da dor foi obtido com uma infusão de anestésico local em baixa concentração.

ABSTRACT

Objective To compare the postoperative analgesic effect between serratus plane block and thoracic paravertebral block in patients undergoing thoracoscopic surgery.Methods Sixty patients undergoing thoracoscopic surgery, 38 males and 22 females, aged 18-65, BMI 18-25 kg/m2, falling into ASA physical status I or II.They were divided into groups S and T by random number table, 30 cases in each group.Two groups of patients were treated with general anesthesia with endobronchial intubation and PCIA after operation.Group S performed Ultrasound-guided serratus plane block and group T performed thoracic paravertebral block, 0.4%ropivacaine 30 ml were used in the two groups.The two groups of patients were observed 30 min after block, and the sensory block plane was measured with acupuncture and recorded.Recording operation time, onset time and duration of the block.Resting and cough VAS score were recorded at 2, 4, 8, 12, 24, and 48 hafter surgery.The first pressing time of the analgesic pump and times of press analgesic pump, the amount of sufentanil used and times the number of cases of useing piperidine were recorded within 48 hafter operation.Block related complications and analgesic related adverse reactions were recorded.Results Compared with group T, the operation time of the block obviously shortening but the duration obviously lengthening (P<0.01).Resting and cough VAS score at 12 hafter surgery significantly was lower (P<0.01).The first pressing time of the analgesic pump obviously lengthening, the number of press analgesic pump and the amount of sufentanil used significantly were reduced (P<0.01) in group S.Conclusion Ultrasound guided SP block and TPVB block can provide good postoperative analgesia for patients undergoing thoracoscopic surgery, but SP block is more durable, with less operation time and complications than TPVB block, and can effectively reduce the opioid demand and incidence of nausea and vomiting after operation.

ABSTRACT

This paper pretends to demonstrate the effect of the combination of transversus abdominis plane block (TAP block) and Serratus plane block (SP block) techniques in analgesia of 4 dogs undergoing total unilateral mastectomy. Dogs were premedicated with methadone (0.5mg.kg-1) intramuscularly. Anesthesia was induced with propofol (6mg.kg-1) and midazolam (0.3mg.kg-1) and maintained with isoflurane. SP and TAP block were performed unilaterally using ultrasound by the injection of bupivacaine 0.25% (0.3mL kg-1) diluted with NaCl solution 1:1. Heart rate (HR), respiratory rate (f), non-invasive arterial pressure, esophageal temperature (T), oxygen saturation (SpO2) and electrocardiogram were monitored continuously. Animals were monitored for two and four hours after extubation for pain by using the Canine Acute Pain Scale from Colorado State University. Two hours after extubation, tramadol (4mg.kg-1) and dipyrone (25mg.kg-1) was administered to all dogs. It was not observed any alteration on cardiac rhythm. HR, f, T and mean arterial pressure remained below the preincisional values for all dogs. No dog required intraoperative rescue analgesia. Recovery from anesthesia was without any complication. All animals scored 0 (0/5) at pain scale, two and four hours after extubation and none of them expressed concern over the surgical wound. Dogs were able to walk before two hours after extubation. The combination of both techniques is effective in anesthetic blocking the thoracic and abdominal walls and it is suggested both may be included in the multimodal analgesia protocols for this type of surgery.(AU)


Este trabalho pretende demonstrar o efeito analgésico da combinação das técnicas de bloqueio do plano transverso abdominal (TAP block) e bloqueio do plano serrátil (SP block) em 4 cadelas submetidas à mastectomia unilateral total. Os animais foram pré-medicados com metadona (0,5mg.kg-1) por via intramuscular. A anestesia foi induzida com propofol (6mg.kg-1) e midazolam (0,3mg.kg-1) e mantida com isoflurano. Os bloqueios SP e TAP foram realizados unilateralmente, utilizando ultrassonografia, pela injeção de bupivacaína a 0,25% (0,3mL.kg-1), diluída com solução de NaCl a 1:1. A frequência cardíaca (FC), frequência respiratória (f), pressão arterial não invasiva, temperatura esofágica (T), saturação de oxigênio (SpO2) e eletrocardiograma foram monitorados continuamente. Os animais foram monitorizados durante duras e quatro horas após a extubação para a dor usando a Escala de Dor Aguda Canina da Universidade Estadual do Colorado. Duas horas após a extubação, tramadol (4mg.kg-1) e dipirona (25mg.kg-1) foram administrados a todos os cães. Não foi observada qualquer alteração no ritmo cardíaco. HR, f, T e pressão arterial média permaneceram abaixo dos valores basais para todos os cães. Nenhum cão requereu resgate analgésico intra-operatório. Não houve complicações na recuperação anestésica. Todos os animais apresentaram escore 0 (0/5) na escala de dor, duras e 4 quatro horas após a extubação e nenhum expressou desconforto com a ferida cirúrgica. Todos os cães foram capazes de caminhar antes de duas horas após extubação. A combinação de ambas as técnicas é eficaz no bloqueio anestésico das paredes torácica e abdominal e sugere-se que ambos podem ser incluídos nos protocolos de analgesia multimodal para este tipo de cirurgia.(AU)

ABSTRACT

Objective To investigate the effect of ultrasound-guided serratus plane block on ef-ficacy of postoperative analgesia in patients undergoing radical mastectomy.Methods Forty ASA physical status Ⅰ or Ⅱ patients aged 45-65 years scheduled for radical mastectomy under general an-esthesia were randomly divided into two groups (n = 20 each):SP block group (group SP)and control group (group C).After induction of anesthesia,ultrasound-guided homolateral SP block were performed,and 0.375% ropivacaine 20 ml was injected in group SP,while the equal volume of normal saline was used instead in group C.The patients received patient-controlled intravenous analgesia (PCIA)with sufentanil after operation in the two groups.The scores of prince henry pain scale (PHPS)were evaluated at 2,4,8,12 and 24 h after operation.The consumption of sufentanil, propofol and remifentanil were recorded,meantime the times of successfully delivered doses (D1)and attempts (D2 )within 24 h after operation were added up,calculating D1/D2.The adverse effects were also recorded.Results The scores of PHPS at postoperative 2 h [(1.3±0.4)scores vs.(3.0±0.5) scores],4 h [(1.4 ± 0.5 )scores vs.(2.9 ± 0.7 )scores],8 h [(1.7 ± 0.6 )scores vs.(2.7 ± 0.6 ) scores],and the consumption of sufentanil [(54±17)μg vs.(88±25)μg],remifentanil [(287±41)μg vs.(375±66)μg]were significantly lower in group SP than in group C,while D1/D2 (0.88 ±0.11 vs. 0.56±0.17)was higher (P <0.05).There were no adverse reactions in both groups.Conclusion Ultra-sound-guided SP block reduces the perioperative opioids consumption and enhances the efficacy of postopera-tive analgesia in patients undergoing radical mastectomy.
